mo-lokg mA = 1kg UA = 20m/s UB=0 After collesion 1. momentum conserved Maua+MBUR = MAVA + more 9x20 + loxo = 1X VAT lovu 7 VAPart-2 Ng=3%ms W = 0 from newtons equation of mosion V = wt at from FBD of Block & x = Mafn 7 x = 0.4x10x10 auon t = -ma -Mainly concepts involved in this question are:

1. Conservation of momentum in collision

2. Conservation of Energy in Collision

3. Newton's equations of motion

    A steel ball of mass m = 1 kg and a cord of negligible mass and length L = 2 m make up a simple pendulum that can pivot without friction about the point O (see below). This pendulum is released from rest in a horizontal position and when the ball is at its lowest point it strikes a block of mass m = 1 kg sitting at rest on a shelf. Assume that the collision is perfectly elastic and...
