PLEASE HELP A ball of mass m = 0.27 kg and velocity v = 5.2 m/s collides head-on with a ball of mass M = 0.93 Kg that is initially at rest. If the collision is elastic, determine the velocity of the two balls.​

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
