Problem P. 4056. (March 2008)
P. 4056. An object of mass m is projected vertically up with a speed of v0. At the same moment another object of mass M, which is initially above the projected one, is dropped from a height of h. The two pointlike objects collide totally inelastically, and they stick to each other.
With what speed will they hit the ground?
(Data: m=1.25 kg, v0=19 m/s, M=2 kg, h=20 m.)
