A solid uniform spherical boulder travels down a hill. At the top of thehill the boulder is rolling with a horizontal speed of 5 m/s. The top halfof the hill is rough, so that the boulder continues to roll without slipping.The bottom half of the hill and the valley is covered in smooth ice, sothat there is no static friction between the boulder and the hill. How fastis the boulder moving when it gets to the bottom of the hill? What is itsrotational speed in the valley if the boulder has a radius of 10 cm?Rough50.0 mSmooth

Flywheels are large, massive wheels used to store energy. They can be spun up slowly, then the wheel's energy can be released quickly to accomplish a task that demands high power. An industrial flywheel has a 1.6 m diameter and a mass of 270 kg. Its maximum angular velocity is 1600 rpm. A motor spins up the flywheel with a constant torque of 56 Nm. How long does it take the flywheel to reach top speed? How much energy is stored in the flywheel? The flywheel is disconnected from the motor and connected to a machine to which it will deliver energy. Half the energy stored in the flywheel is delivered in 2.4 s . What is the average power delivered to the machine? How much torque does the flywheel exert on the machine?

A ball of radius 0.200 m rolls with a constant linear speed of 2.65 m/s along a horizontal table. The ball rolls off the edge and falls a vertical distance of 2.30 m before hitting the floor. What is the angular displacement of the ball while the ball is in the air?
A top-loading washing machine has a cylindrical basket that rotates about a vertical axis. The basket of one such machine starts from rest and reaches an angular speed of 7.0 rev/s in 10.0 s. The lid of the machine is then opened, which turns off the machine, and the basket slows to rest in 9.0 s. Through how many revolutions does the basket turn during this 19 s interval? Assume constant angular acceleration while it is starting and stopping.
A “blink of an eye” is a time interval of about 150 ms for an average adult. The “closure” portion of the blink takes only about 55 ms. Let us model the closure of the upper eyelid as uniform angular acceleration through an angular displacement of 14.0°. What is the value of the angular acceleration the eyelid undergoes while closing?
