I 2) 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-* s and then decreases linearly to o in another 10- s. (The moment of inertia for a solid ball ismR?) a) What is the...

Problem 4 A uniform solid spherical ball of mass M and radius R rests on a horizontal surface. Assume a constant coefficient of friction (this means that the frictional force is equal to the normal force multiplied by u). The acceleration due to gravity is g. At time t 0, the bal is struck impulsively on center, causing it to go instantaneously from rest to initial rotation horizontal speed vo with a no (a) Find the horizontal speed, and the...

A spherical bowling ball with mass m = 4 kg and radius R = 0.114
m is thrown down the lane with an initial speed of v = 8.7 m/s. The
coefficient of kinetic friction between the sliding ball and the
ground is ? = 0.32. Once the ball begins to roll without slipping
it moves with a constant velocity down the lane.

8) A uniform hollow spherical ball of mass 1.75 kg and radius 40.0 em is rolling up a ramp that rises at 30.0° above the horizontal. Speed of the ball at the base of the ramp is 8.20 m/s. Moment of inertia of hollow sphere is given by I-(2/3)m r. (a) What is the angular velocity of the ball at the base of the ramp? (b) Determine how far up the ramp does it roll before it starts to...

A solid uniform sphere of radius 0.76 cm and a mass of 0.87 kg is held against a spring compressed a distance of 6.0 cm from its resting length. After release, the sphere leaves the spring and rolls down the flat, horizontal table with a translational velocity of 3.9 m/s. a) What is the force constant of the spring? b) If the ball then rolls up a ramp inclined at 22 degrees, how far along the ramp does it travel?
