Unformatted text preview: THE NEXT PAGE. 6 2006 AP® PHYSICS B FREE-RESPONSE QUESTIONS (Form B) 2. (15 points) A small block of mass M is released from rest at the top of the curved frictionless ramp shown above. The block slides down the ramp and is moving with a speed 3.5u0 when it collides with a larger block of mass 1.5M at rest at the bottom of the incline. The larger block moves to the right at a speed 2u 0 immediately after the collision. Express your answers to the following questions in terms of the given quantities and fundamental constants. (a) Determine the height h of the ramp from which the small block was released. (b) Determine the speed of the small block after the collision. (c) The larger block slides a distance D before coming to rest. Determine the value of the coefficient of kinetic friction m between the larger block and the surface on which it slides. (d) Indicate whether the collision between the two blocks is elastic or inelastic. Justify your answer. © 2006 The College Board. All rights reserved. Visit
