An object of mass 3m is launched in vertical direction with velocity Vo. At the same time from the maximum height the 3m object can reach another object of mass m is released without initial velocity. Two objects experience perfectly inelastic collision at some height. Given that Vo = 12m/s and m = 150g. Calculate the time when the two objects collide. What is the velocity of each just before the collision? What is the height where the collision takes place? How much kinetic energy is lost in the collision? I've calculated the max height H to be 7.3m but I'm stuck on calculating the time and velocity and all the rest. Can anyone help? Thanks!
