  1. A uniform solid ball has a mass of 20 g and a radius of 5 cm. It rests on a horizontal surface. A sharp force is applied to the ball in the horizontal direction 9 cm above the surface. The force rises linearly from 0 to a peak value of 40,000 N in 10^-4 s and then decreases linearly to 0 in another 10^-4 s. (The moment of inertia for a solid ball is (2/5)mr^2 )
  1. What is the velocity of the ball after the impact?
  2. What is the angular velocity of the ball after the impact?
  3. What is the velocity of the ball when it begins to roll without sliding. (This means v=Rw).
  4. For how long does the ball slide on the surface given the coefficient of kinetic friction uk=0.5.

A steel pinball of mass ? = 150 g and radius ? = 1.50 cm is shot along a level horizontal surface with initial speed ?0 = 7.00 m/s. Initially the pinball is not rotating, but it quickly catches the surface and begins to roll smoothly without slipping. The pinball then encounters a ramp with 30.0o slope and is launched at a 2.00 cm height. Determine the horizontal distance the ball travels while in the air, assuming there are no...

A solid ball of mass 5.50 kg and radius 2.7 cm compresses a spring of constant 1100 N/m (point A) (Ball is at rest). The ball then rolls along a frictionless surface and goes up an incline (starting at point B) to the top where is stops (points C). At point B the ball is moving with a linear speed of 2.40 m/s. Find distance the spring is compressed. (point A) Find the max height for the ball to stop...

A small, solid cylinder with mass = 20 kg and radius = 0.10 m starts from rest and rotates without friction about a fixed axis through its center of mass. A string is wrapped around the circumference of the cylinder and pulled using a constant force F. The resulting angular acceleration of the cylinder is 5.0 rad/s2. (The moment of inertia of the cylinder is 1/2 MR^2.) 1. What's the force F, in Newtons? 2. What's the angular velocity after...

A bowler throws a bowling ball of radius 11cm down a bowling lane. It has an initial linear velocity of 8.8 m/s, but no initial angular velocity. The kinetic friction force causes both linear acceleration and an angular acceleration; the kinetic friction coefficient between the ball and the floor is 0.1. When the balls linear speed has decreased enough and the ball’s angular speed has increased enough there will come a moment when the ball’s contact point with the floor...
