Solving a problem in physics section 29 point 74 mechan

74. A steel ball of mass m = 20 g is put on the spring balance mass M = ´40 This pan deviated by x0 = 3 cm. Determine the maximum indications of weights, if the ball throw on the scales without initial velocity from a height of h = 40 cm and after the impact, he jumped to a height h1 = 17 cm. blow considered absolutely elastic.
