- A bowl is rotating on a potter's wheel at constant angular speed as shown. The friction force between his hands and the bowl is 1.70 N total. If the bowl has a diameter of 13.0 cm, how large is the torque on the wheel? Report a positive answer.A 3 kilogram solid sphere with a radius of 15 centimeters rolls without slipping down a rough incline with a 35 degree angle. If the sphere rolls from rest from a height of 45 centimeters, determine the sphere's translational speed at the bottom of the incline. Also, draw the free body diagram. Also see the attached picture that goes with the problem. Thank you.A solid 0.6350 kg ball rolls without slipping down a track toward a vertical loop of radius ?=0.6350 m. What minimum translational speed ?min must the ball have when it is a height ?=0.9944 m above the bottom of the loop in order to complete the loop without falling off the track? Assume that the radius of the ball itself is much smaller than the loop radius ?. Use ?=9.810 m/s^2 for the acceleration due to gravity.

- A solid cylinder of radius R rolls without slipping on a horizontal plane. The velocity of its CM is V=2m/s. Then the cylinder rolls uphill, also without slipping. What maximal height h, will the cylinder reach? plz show step by step on how you acquired the formula you are using for this problem!!! Thank YouA solid cylinder with mass m, radius R, and rotational inertia I (about its center) is released from rest and rolls down a ramp. Friction between the bottom of the cylinder and the ramp causes the cylinder to roll without slipping. The linear acceleration of the cylinder is a. Which TWO of the equations below are correct for this scenario? The equations are in terms of m, I, R, and a, as well as f (the force of static friction between the cylinder and the ramp) and g. (You must pick BOTH of them to get this question correct!) f = ma mg sin θ = ma mg sin θ - f = ma f R = I (a/R) mg sin θ - f = I (a/R) R mg sin θ = IaRYour answer is partially correct.
