Name: Date: I'd: Practice 10.1: Rotational Dynamics Question 1 cube of ice, a wheel, and a solid sphere are all placed at the top of a ramp. All objects have the same mass M. The sphere and wheel each have the same radius of R. The objects are released from rest: the cube slides without friction, and the wheel and sphere both roll without slipping. (a) and (b) Draw a free-body diagram showing the forces acting on the objects. Your vectors should reflect the relative size of the forces and should originate at the point where the force is applied. (a) Cube (b) Wheel or Sphere O (c) The cube reaches the bottom of the ramp before either round object. i. Write two Newton's Second Law equations: one for the cube and one for the round object Cube Wheel or Sphere ii. Explain why the cube reaches the ground before either round object. Refer to your FBDs and your NZL equations, as well as other rules/equations as appropriate. (d) At and At refer to the time it takes for the wheel and sphere to reach the bottom of the ramp. Compare the two times and explain your reasoning
