Momentum and CollisionMedium
Question
A ball collides with an inclined plane of inclination θ after falling through a distance h. If it moves horizontally just after the impact, the coefficient of restitution is :
Options
A.tan2θ
B.cot2θ
C.tanθ
D.cotθ
Solution
e =
apply conservation of momentum
m
= m v cos θ ......(i)e cosθ × m = mv cosθ ......(ii)
= cotθ.∴ e = tan2θ on solving
