Answer the following and show the Illustraion each problem

2. A 4.6 kg block resting on a smooth horizontal surface is attached to a string that passes
over a frictionless pulley as shown in the figure. The pulley has a radius of .48 m. a force of
8.5 N pulls the other end of the string. As a result, the block moves a distance of .35m starting
form rest. Find the following:
a. Acceleration of the block
b. Angular acceleration of the pulley
c. Moment of inertia of pulley
