Question

A 100g ball having speed 10 m/s collides with a wall at an angle 30° and rebound with the same angle and the contact period between the ball and wall is 0.1sec,then the force experience by the wall is​

Answer 1

Answer:

F=change in momentum/time

change in momentum=

$2mv \sin( \alpha )$

2*0.1*10* sin30=1

F=1/0.1=10N
