A smooth steel ball strikes a fixed smooth steel plate at an angle theta with vertical.If coefficient of restitution is e find rebounce angle?

look its actually easy jus need to explain if it comes in board if for iit type solving then heres the solution

e = v2 -v1/u1 - u2 on simplyfing we get

-u1e = v1

here the case just a bit different ...all u need to do split the velocit into vector then divide it will give u

etan theta = tan theat

therefore angle of rebound will be

tan theta = tan theta/e
