a simple pendulum consists of a 1.5 kg mass connected to a cored without and mass or friction. Initially the pendulum is vertically positioned when a 2.0 kg mass collides with ie, causing the pendulum to displace vertically upward 1.25 m. After the collision, the 2.0 kg mass travels along the frictionless horizontal surface, until it meets a 30.0 degree incline with a coefficient of kinetic friction of .400. if the ,as travels a max distance of 1.125 m up the incline what is the initial velocity that the 2.0 kg mass strikes the pendulum with?
