Car "X" is travelling at half the speed of car "Y" and mass of car X is twice as compared to the mass of car 'Y". Which of the following statements is correct?
Correct answer: A. Car "X' has half of the kinetic energy of car "Y'
- A. Car "X' has half of the kinetic energy of car "Y'
- B. Car "X" has one quarter of the K.E of car "Y"
- C. Car 'X" has twice the K.E of car "Y'
- D. The two cars have the same KE
Explanation
Car X speed = v/2 amd mass = 2m Car Y speed = v and mass = m

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
