At what speed does a 1800 kg compact car have the same kinetic energy as a 2.00 104 kg truck going 25.0 km HR?
The car must be traveling 65.59 km/hr to match the kinetic energy of the truck.
Which has more momentum a 1000 kg car moving 1m s or a 70kg person sprinting at 8m s?
Expert-Verified Answer A 1000 kg car moving 1 m/s have more momentum which is 1000 kg meters per second.
Which has more momentum a truck that is parked or a falling raindrop?
Answer: The raindrop has more momentum because a supertanker at rest has zero momentum. The Penguins goalie Matt Murray stopped a slap shot traveling at 48.0 m/s in 0.02 s. The mass of the puck was 160 g.
When the change in momentum occurs over a long time the force of impact is large?
If the change in momentum occurs over a long time, the force of impact is small. If the change in momentum occurs over a short time, the force of impact is large. When hitting either the wall or the haystack and coming to a stop, the momentum is decreased by the same impulse.
What is the speed of 500 kg car that has a kinetic energy of 64 kJ?
Kinetic Energy (KE) = 64 kJ = 64 × 103 J. ∴ Speed of the car = 16 m/s.
What is the kinetic energy of car having mass 1000 kg?
Kinetic energy of a car, having mass 1000 kg is 1,12,500 J. Driver applies brakes when an obstacle is sighted and car comes to halt after travelling 100 m distance (without meeting with an accident).
Which has a greater momentum a 1000 kg truck at rest or a 100 kg bicycle in motion?
Taking the formula for momentum to be p=mv this is the mass multiplied by the velocity. Although the semi truck certainly has a larger mass, it is not in motion and therefore does not have any momentum. The bicycle however has both mass and velocity and therefore has the larger momentum of the pair.
At what speed does a 1000 kg compact car have the same kinetic energy as a 20000 kg truck going 25km h?
Final answer: A 1000 kg compact car needs to travel at approximately 111.8 m/s to have the same kinetic energy as a 20,000 kg truck traveling at 25 km/hr. Explanation: The kinetic energy (KE) of an object is given by the formula KE = 0.5*m*v², where m is the mass of the object and v is its velocity (speed).
Who has more momentum if a 70 kg man and a 40 kg boy are both running at the same velocity?
The concept in question relates to the physics of momentum, which is a measure of an object’s mass in motion. It is calculated by multiplying an object’s mass by its velocity. Hence, if a 70kg man and a 40kg boy are running at the same velocity, the man would have greater momentum because he has a larger mass.
Does rain have momentum?
Answer and Explanation: When the rain falls from the sky with a certain velocity it has a certain value of momentum but as it hits the ground its velocity is reduced to zero and the momentum of the rain reduces to zero. In other words, the momentum of the rain is countered by the force exerted by the ground.
Who has more momentum?
Both the mass and velocity of an object impact momentum. As a result, less massive objects can have more momentum than more massive objects (if the less massive object is moving faster), and slower objects can have more momentum than faster objects (if the slower object has more mass).
Which vehicle has more momentum?
You probably guessed that it takes more force to stop a large truck than a small car. In physics terms, we say that the truck has greater momentum. Velocity is a term that refers to both speed and direction.
Does impulse equal momentum?
An object’s change in momentum is equal to its impulse. Impulse is a quantity of force times the time interval. Impulse is not equal to momentum itself; rather, it’s the increase or decrease of an object’s momentum.
What are 2 ways to increase impulse?
Impulse can also be increased by increasing the time interval or by increasing the magnitude of change in momentum. The change in momentum can be increased by increasing the velocity of the body.
Does more momentum mean more force?
Momentum changes with the change in velocity whereas force changes with the change in acceleration. The longer a force is applied, the larger the momentum is. These quantities are vector quantities meaning they both have magnitude and direction.
At what speed does a 1800 kg compact car have the same kinetic energy as a 16000 kg truck going 21 km h?
Expert-Verified Answer The compact car needs to have a velocity of approximately 60.61 km/h to have the same kinetic energy as the truck going at 21 km/h.
At what speed does a 2000 kg compact car have the same kinetic energy as a 18000 kg truck going 21 km hr?
Final answer: The 2000 kg compact car would need to be moving at approximately 195.9 km/hr to have the same kinetic energy as an 18000 kg truck moving at 21km/hr.
What is the kinetic energy of a 1000 kg car has a velocity of 17 miles per second?
Answer: The kinetic energy of the car is 144, 500 Joules.
