What is a truck weighing 2500 kg and moving with a velocity of 21m s?
A truck weighing 2500 kg and moving with a velocity of 21 m/s collides with a stationary car weighing 1000 kg. The truck and car move together after the impact. Calculate their common velocity? (Ans: 15 m/s )
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 large truck and a car are moving with the same velocity have a head?
because force and time is same for both the truck as well as car; so the change in momentum of truck is equal and opposite to change in momentum of car. A 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.
What is the truck velocity relative to the car?
Now, recall that for two bodies 𝐴 and 𝐵 moving with velocities 𝑉 𝐴 and 𝑉 𝐵, the relative velocity of 𝐴 with respect to 𝐵 is 𝑉 𝐴𝐵, which is 𝑉 𝐴 minus 𝑉 𝐵. Applying this to our car and truck then, we have 𝑉 𝑡𝑝 — that’s the relative velocity of the truck with respect to the car — is equal to 𝑉 𝑡 minus 𝑉 𝑝.
What is the momentum of a 1200 kg car with a velocity of 25 m s?
Answer and Explanation: We can find the momentum of the car by multiplying the mass times the velocity. Because both the mass and velocity are given in SI units, we do not need to perform any unit conversion before multiplying. Hence, we have shown that the momentum of the car is 30000 kg m/s.
What is the momentum of a 2000 kg truck that moves at 10 ms?
Momentum before the collision is p=mv=2000⋅10=20,000 kgms−1 .
Are car and a lorry moving with same velocity if same break force is applied?
Hence, the car will travel more distance comes to rest than that of lorry. Was this answer helpful?
What is the velocity of a moving vehicle?
The velocity of a moving car is given by v = X t + Y t where v is the velocity and t is the time. Then the SI units of X and Y respectively will be: m ; ms.
When two objects are moving at the same velocity?
Objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities.
When an object is moving its velocity and acceleration are always in a same direction?
The acceleration points in the same direction as the velocity if the car is speeding up, and in the opposite direction if the car is slowing down.
When two objects are moving at the same velocity with different masses which has a higher kinetic energy?
Kinetic energy is 1/2 mv2 which is like ½ x momentum x velocity. Since they have the same momentum, the object with the larger velocity has a larger kinetic energy – that’s the object with the small mass. It would take a longer distance to stop it with the same force.
Is velocity the same for both objects after collision?
In a perfectly inelastic collision, the two objects stick together and move as one unit after the collision. Therefore, the final velocities of the two objects are the same, v 1 ′ = v 2 ′ = v ′ . Thus, m 1 v 1 + m 2 v 2 = ( m 1 + m 2 ) v ′ .
What is the formula for the velocity of a car?
Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.
What is the difference between speed and velocity?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.
What is the formula for relative velocity?
What is relative velocity formula? The formula to calculate the relative velocity of an object with respect to another is Vab= Vb-Va, where Vab is the relative velocity of object A with respect to object B and Vb and Va are the velocities of the objects with respect to a third observer.
Is a car of mass 2400 kg moving with a velocity of 20 meters per second is stopped in 10 seconds?
A car of mass 2400kg moving with a velocity of 20 m/s is stopped in 10… Therefore, the retardation of the car is 2 m/s². Therefore, the retarding force acting on the car is 4800 N.
What is an object of 10 kg is moving with a speed of 2 meters per second?
Speed of the object (v) = 2 m/s. Kinetic Energy (K.E) = ½ mv2. = ½ (10)(2)2 ⇒ 20 joules. The kinetic energy of the object is 20 J.
How much work is done to stop a car weighing 1500 kg moving with a speed of 60 km h?
Hence, work required to stop the car =12×1500×16.662 =208166.7J=208.17kJ. Was this answer helpful?
How do you find weight from velocity?
Acceleration = net force ÷ body mass (body weight ÷ the acceleration of gravity [9.81 m/s/s]) Velocity = acceleration × time.
