Hello people. New here and i've got a problem here which i would appreciate some help with. Situation : A ball of mass 300g is attached to a massless string of 0.2m suspended at a 90 degree angle to another ball of mass 500g held by a massless string at length 0.2m. Imagine the ball A (0.3kg) is positioned next to ball B, which are equal except for masses. Ball A is moved in a quarter of a circle motion up 0.2m, keeping it's string straight. That is the case we are examening. The question is, what are the maximum heights ball A and B can attain after ball A is released collides with B? We assume that this is an insulated system, meaning 100 % conserved energy and momentum. Through PEi + KEi = PEf + KEf We achieve the velocity 1.98 m/s right before collision with ball B. The problem arises when the total KE for the system has to be distributed correctly between ball A and B post-collision. I've reached the point where the KEi = Va final + 5/3 Vb final How do you go about finding either one of the velocities? I know that the V of B will be greater than V of A since B has less than double the mass of A Appreciate your help!
