A tennis ball of mass m is hit against a wall. It hits the wall at velocity u and rebounds in the direction it came from at velocity v .
Which formula gives the change in momentum of the tennis ball?

Question

A tennis ball of mass m is hit against a wall. It hits the wall at velocity  u  and rebounds in the direction it came from at velocity  v . 
 Which formula gives the change in momentum of the tennis ball?

Answer

Δ p  = m v  + m u  (where  p ,  v , and  u  are vectors)

Answer

Δ p  = m v  - m u  (where  p ,  v , and  u  are vectors)

Answer

Δp   = mv  -  mu (where p, v, and u are not vectors)
