A 1 kg ball is attached to a 2 m long piece of very light string and suspended in such a way that it can freely swing and it passes just above the ground. A 2 kg block is placed on the ground so that the 1 kg block will collide with it when the cord is horizontal, as shown below. The coefficient of kinetic friction between the block and the ground is .1 A) Calculate the angle from the vertical at which the 1 kg ball must be raised so that, when the two masses collide elastically, the 2 kg block will travel 6 meters before stopping. B) If the 1kg ball is raised so that the cord is horizontal, and the two masses collide elastically after it is released , completely describe the motion of the two masses after the 1 kg ball is released.
