Question

A block is on an incline with a heighth of.60 meters. Suppose that a block m = .050kg, sometime afterreaching the base of the incline, undergoes a completely inelasticcollision with the stationary block M = .075kg. Use the principleof conservation of linear momentum to determine the common speed ofthe blocks just after the collision. ___________? A block is on an incline with a heighth of.60 meters. Suppose that a block m = .050kg, sometime afterreaching the base of the incline, undergoes a completely inelasticcollision with the stationary block M = .075kg. Use the principleof conservation of linear momentum to determine the common speed ofthe blocks just after the collision. ___________?

Explanation / Answer

height of the block 1 is   h = 0.6 m Speed of the block 1 at the bottom  u = [ 2gh]                                                        = 3.429 m / s initial speed of the block 2 is U = 0 m / s from law of conservation of momentum , m u +MU = ( m + M) v                                                                       m u = ( m + M ) v from this common speed v = mu / ( m + M )                                         = 1.371 m / s
