I´m working on a physics hand-in and found the relative angle between the two balls after collison(where one is stationary before the collison) to be exactly 90degrees, is this random or is it always so?
It´s worth mentioning that total momentum and kinetic energy is conserved.
The hand in is...
Hi, I am having problems solving the last problem(see attached files), i have derived these equations which i thought should would help me solve the problem but i seem to be stuck.
U=(H3-H4)/(d4-D4)
Height at t
h and H3 are the same so i set H(initial)=0
-0,5gt^2+vsin(θ)t=-u*3*cos(θ)vt...
