Arubber ball and a lump of clay have equal mass. they are thrown with equal speed against a wall. the ball bounces back with nearly the same speed with which it hit. the clay sticks to the wall. which one of these objects experiences the greater momentum change?

The ball experiences the greater momentum change

Explanation:

The momentum change of each object is given by:

where

m is the mass of the object

v is the final velocity

u is the initial velocity

Both objects have same mass m and same initial velocity u. So we have:

- For the ball, the final velocity is

Since it bounces back (so, opposite direction --> negative sign) with same speed (so, the magnitude of the final velocity is still u). So the change in momentum is

- For the clay, the final velocity is

since it sticks to the wall. So, the change in momentum is

So we see that the greater momentum change (in magnitude) is experienced by the ball.
