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.)
