Question

a mass on moving with velocity u hits a surface at an angle theta with normal to surface. how much impulse does the surface exert

Answer 1

Answer:

Here initial velocity is u and final velocity is v

u is making angle θ and v is making angle ϕ with x−axis

The impulse J acting on the ball is along common normal (y−axis)

⟹x−component of initial velocity ,ucosθ will remain unchaged

⟹V  

x

​  

=ucosθ

for V  

y

​  

 we will use coefficient of restitution
