You have a frictionless ramp that starts at a height of 2.0 m. You have three objects at the top: (1) a block which slides down the ramp (no friction) and (2) a solid sphere and (3) a solid cylinder which both roll down the ramp without sliding.
Assuming they start from rest, find the final velocity of all three objects at the bottom of the ramp.
Which one reaches the bottom first?
Briefly explain why they arrive at different speeds even though energy is conserved for all three.

- Learning Goal: To understand the kinetic energy of a rigid body undergoing translational motion, rotation about a fixed axis, or general motion in the plane. Consider the rigid body shown in the figure. (Figure 1) An arbitrary th particle of the body, having mass dm, is located a distance r from an arbitrary point P in the inertial x-y reference plane. If, at the instant shown, the particle has a velocity vi, then the particle's kinetic energy is T₁ = 1/(dm) v². The kinetic energy of the entire body is found by summing similar equations for each particle in the body. As the number of particles increases, by letting the size of each particle go to an infinitesimally small volume, the sum becomes an integral and the kinetic energy of the body is T = 1/2 √m dm v ².
