2-Consider a frictionless track as shown in the ﬁgure below. A block of mass m1 = 5.00 kg is released from®. It makes a head—on elastic collision at ®with a block of mass m; = 10.0 kgthat is initially at rest. El Hint: search for the ﬁnal velocity formulas in an elastic collision.Use conservation of energy between potential energy and kinetic energy. 1- What is the velocity of mass m1 before the collision? 2- What is the velocity of mass m, after the collision? 3- What is the velocity of mass 4712 after the collision?
