Physics

Object 1 is held at rest at the top of a rough inclined plane oflength ? = 1.5 ? and angle ? = 25∘. When it is released, it moveswith an acceleration of 2 ? down the plane. a) Find the coefficientof kinetic friction ?? of the inclined plane. (??) b) Find thespeed of Object 1 when it reaches the bottom of the plane. (??) Atthe bottom of the inclined plane, Object 1 arrives at a smooth(frictionless) horizontal surface where it hits Object 2 of threetimes mass of Object 1 (?2 = 3?1). c) Assuming an elasticcollision, find the speeds of Objects 1 and 2 just after thecollision
