Fig. 9-9. A 500-g steel ball embeds itself into the clay causing both . to rise a height of 20 cm. Find the entrance velocity of the ball? Before applying momentum conservation, we need to know the common velocity of the clay and ball after the collision. Energy is conserved : ½(m1 + m2) vc2 = (m1 + m2) gh ; vc = 1.98 m/s
