When a large truck and a car are moving with the same velocity have a head-on collision?
(d) The car is likely to suffer more damage than the truck, as is is lighter. The acceleration, i.e., change in velocity of the car is more than that of the truck. Q. A large truck and a car, both moving with a velocity of magnitude v, have a head-on collision and both of them come to a halt after that.
Does a large truck and a small car are moving at the same speed have the same kinetic energy?
A large truck moving at the same speed as a small car has more kinetic energy than the car. The kinetic energy (KE) of an object depends on its speed and its mass.
Which has a greater momentum a truck and a car moving at the same velocity?
The truck has more momentum than the car. By momentum, we mean inertia in motion. Momentum is the mass of an object multiplied by its velocity. A moving truck has more momentum than a car moving at the same speed because the truck has more mass.
When a truck and a car are moving with the same momentum?
If the momentum of car and truck is the same ( P car = P truck ) then the speed of the car is greater than the speed of the truck. ( V car > V truck ) . This is because at constant momentum the mass is inversely proportional to the velocity of the object.
When a truck and a car traveling at the same speed collide head on the impact force?
On collision both the car and the truck experience equal force of impact because action and reaction forces are equal.
What happens when two objects that weigh the same collide at the same speed?
Both momentum and kinetic energy are conserved quantities in elastic collisions. Suppose two similar trolleys are traveling toward each other with equal speed. They collide, bouncing off each other with no loss in speed. This collision is perfectly elastic because no energy has been lost.
How can a large truck and a small car have the same momentum?
When would a small car have the same amount of momentum as a large truck? When the speed of the car is much greater than the speed of the truck.
Is the momentum transferred from the truck to the car is equal and opposite to the momentum transferred from the car to the truck?
The change of momentum for the car is more than the change of momentum for the truck, but the changes are equal and opposite leading to the conservation of momentum. The way you have written the change in momentum, both vehicles continue moving in the same direction after the collision as they did before.
Will acceleration have a greater impact on the of a large truck than a small car?
Correct answer: The car and the truck experience equal and opposite forces, but since the car has a smaller mass it will experience greater acceleration than the truck according to the equation F = ma. A greater mass will decrease the acceleration.
When a car and truck are moving with the same velocity?
If a car and Truck move with Same velocity and we applied Force on both, the car will come at rest first. Explanation: We know that momentum of a body depends on the mass and velocity of the body. The velocities on both the car and the truck is same but the mass of truck is more.
When a car and truck are moving with the same velocity in opposite direction?
Expert-Verified Answer 1) the greater force will be experienced by the car because if the mass is greater than the force will be also greater and as the truck has the greater mass as compared to the car so the force exerted by the truck is greater than the car so the car will experienced the greater force of impact.
What happens when two objects with the same mass collide?
When two objects with the same mass collide, Newton’s laws tell us that they will accelerate the same amount but in opposite directions. Recall that force, velocity, and acceleration have both magnitude and direction. We use positive and negative signs to indicate the direction of each of these quantities.
Which has more momentum a huge truck that is not moving or a small toy car that is moving?
Since the truck is not moving, its velocity is zero, and therefore its momentum is also zero. On the other hand, the small toy car that is moving has some momentum because it has both mass and velocity. Therefore, the small toy car that is moving has more momentum than the huge truck that is not moving.
What is impulse equal to?
Impulse ( F Δ t ) Product of the average force exerted on an object and the time interval during which the force is exerted. Impulse is equal to the change in momentum ( ) and is sometimes represented with the symbol .
Which has more momentum a heavy truck?
Answer and Explanation: Linear momentum equals mass times velocity. If the truck has the same speed as the car, then the truck will have greater linear momentum since its mass is several times the mass of the car.
What happens to the velocity of a car during collision?
The only force that acts on the car is the sudden deceleration from v to 0 velocity in a brief period of time, due to the collision with another object. However, when viewing the total system, the collision in the situation with two cars releases twice as much energy as the collision with a wall.
Which will stop first when a car and truck is running with same velocity?
If a car and Truck move with Same velocity and we applied Force on both, the car will come at rest first. Explanation: We know that momentum of a body depends on the mass and velocity of the body.
When two similar vehicles are moving with same velocity?
- When two similar vehicles are moving with the same velocity but with different mass.
- The vehicle having more mass will have more momentum.
- As the momentum of an object depends on the mass and velocity of the body.
- So the vehicle having more mass will require larger force to stop it.
When two similar vehicles are moving with the same velocity on a road such that?
The correct statement would be that when two similar vehicles move with the same velocity on the road, such that one is loaded and the other is empty, more force is required to stop the loaded vehicle.
