Object 1 is held at rest at the top of a rough inclined plane of length = 1.5 and angle = 25∘ . When it is released, it moves with an acceleration of 2m/s^2 down the plane. a) Find the coefficient of kinetic friction of the inclined plane. b) Find the speed of Object 1 when it reaches the bottom of the plane. At the bottom of the inclined plane, Object 1 arrives at a smooth (frictionless) horizontal surface where it hits Object 2 of three times mass of Object 1 (2 = 31). c) Assuming an elastic collision, find the speeds of Objects 1 and 2 just after the collision.
