A disk of mass m, = 70.0 g and radius r , = 4.50 cm slides on a frictionless sheet of ice with velocity v, where v = 12.00 m/s, as shown in a top-down view in figure (a) below. The edge of this disk just grazes the edge of a second disk in a glancing blow. The second disk has a mass m2 = 140 g, a radius r2 = 6.00 cm, and is initially at rest. As the...
