When a heavy particle collides with a light particle at rest, then after collision the target particle moves with:
Correct answer: B. Double the velocity of incident particle
- A. The same speed
- B. Double the velocity of incident particle
- C. Zero velocity
- D. Bounce back with same velocity
Explanation
m1 >> m2 initial v2 is zero after collision v2 = 2v1 as m1 moves with v1 and is heavier than m2

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.
