Momentum and CollisionMedium
Question
A super-ball is to bounce elastically back and forth between two rigid walls at a distance d from each other. Neglecting gravity and assuming the velocity of super-ball to be v0 horizontally, the average force being exerted by the super-ball on one wall is :
Options
A.
B.
C.
D.
Solution
t =
(time for succeesive collision )N × t = dP = mv0 − (−mv0)
N ×
= 2mv0∴ N =
