A uniform hollow spherical ball of mass 1.75 kg and radius 40.0 cm rolls without slipping up a ramp that rises at 30.0 above the horizontal. The speed of the ball at the base of the ramp is 2.63 m/s.
 
  While the ball is moving up the ramp, find (a) the acceleration (magnitude and direction) of its center of mass and (b) the friction force (magnitude and direction) acting on it due to the surface of the ramp.

Question 2

A baseball is located at the surface of the earth. Which statements about it are correct? (There may be more than one correct choice.)
 
  A) The earth exerts a much greater gravitational force on the ball than the ball exerts on the earth.
  B) The ball exerts a greater gravitational force on the earth than the earth exerts on the ball.
  C) The gravitational force on the ball due to the earth is exactly the same as the gravitational force on the earth due to the ball.
  D) The gravitational force on the ball is independent of the mass of the ball.
  E) The gravitational force on the ball is independent of the mass of the earth.
