Question

Set the ground level as zero gravitational potential energy. Use conservation of energy to solve for the final velocity of the sliding block on the frictionless surface (it will be a function of the incline height, ℎ). Note: the block starts from rest. Show your work below or on your own separate page.

3 5. Using conservation of energy, solve for the final translational velocity of the center of mass, ?, of a rolling object with moment of inertia, ?, at the bottom of the incline. The velocity should be in terms of the incline height, ℎ, the mass of the object, ?, the radius of the object, ?, and the moment of inertia, ?. Assume the rolling object starts from rest. 6. Based on the equations you derived above, rank the order that the objects reach the bottom of the incline. (1) reaches the bottom first, (5) is last. _____________ Spherical shell _____________ Solid sphere _____________ Cylindrical shell _____________ Solid cylinder _____________ Frictionless (sliding) cube Run the simulation. Do your results match the simulation?
