Please show your work. Thank you! 31. A pitcher throws a curveball that reaches the catcher in 0.23 s. The ball curves because it is spinning at an average angular velocity of 456 rev/min (assumed constant) on its way to the catcher's mitt. What is the angular displacement of the baseball (in radians) as it travels from the pitcher to the catcher? Note: Express your answer in whole numbers. No unit is required for the final answer.
Note: this problem does not require a kinematics table, as it does not involve the angular velocity changing at all. Both answers only require a single equation which you can find in your book. 3.

A hollow sphere with mass M = 3.0 kg, radius R = 15 cm [note units] rolls without slipping down the inclined plane shown above. The cylinder startsfrom rest at a height H=2.0 m. The inclined plane makes an angle  = 35o with the horizontal.a. On the figure below, draw and label the forces acting on the sphere as it rolls down the inclined plane Your arrow should begin at the pointof application of each force. b. Determine the gravitational potential energy of the sphere. Use the point of contact between the sphere and the ground as a referencepoint. c. Use conservation of energy to determine the linear speed of the sphere at the bottom of the ramp. (e.g. Total Energy at the top of theRamp = Rolling Kinetic Energy at the Bottom of the Ramp + Translational Kinetic Energy at the bottom of the ramp). You will need to usethe fact that sphere is rolling without slipping to determine this. d. If the sphere slid down the ramp (without friction) rather than rolled, would you expect the…
