Question

Consider a head on elastic collision between two objects. Object 1, which has mass m1, is initially in motion, and collides head on with object 2, which has mas2, and is initially at rest. Which of the following statements about the collision are true? (a) If m2>>m1, then the final speed of object 1 is greater than the final speed of object 2. (b)if m1>>m2, then the final speed of object 2 is less than the initial speed of object 1 (c) If m2>>m1, then delta p1 > delta p2 (d)p1 initial =p1 final +p2 final (e)p1 final< p1 initial

Explanation / Answer

(a) If m2>>m1, then the final speed of object 1 is greater than the final speed of object 2
(d)p1 initial =p1 final +p2 final


smaller mass will have more speed after the collision
in elastic collision change in momentum of mass m1 and m2 is equal
