Textbook Question
Chapter 13, Problem 31PQ
Sophia is playing with a set of wooden toys, rolling them off the table and onto the floor. One of the toys is a small sphere with a mass of 0.024 kg and a radius of 0.020 m, and another is a small cylinder that also has a mass of 0.024 kg but a radius of 0.013 m. She rolls each toy so that it has the same translational speed of 0.40 m/s. How much greater is the kinetic energy of the cylinder than the kinetic energy of the sphere?

A Ferris wheel has a radius of 30 m and its centre is 32 m above the
ground. It rotates once every 48 s. Ethan gets on the Feris wheel at the
lowest point and then the wheel starts to rotate. The amount of time it
takes Ethan to reach 38 m above the ground for the first time, to the
nearest tenth of a second, is
S.
Your answer
There is a clever kitchen gadget for drying lettuce leaves after you wash them. It consists of a cylindrical container mounted so that it can be rotated about its axis by turning a hand crank. The outer wall of the cylinder is perforated with small holes. You put the wet leaves in the container and turn the crank to spin off the water. The radius of the container is 15.0 cm. When the cylinder is rotating at 1.64 revolutions per second, what is the magnitude of the centripetal acceleration at the outer wall?
There is a CD-rom that's spinning a CD at 2,000 rpm. There is a bit of dirt, weighing 0.220 g, attached to the CD 3.50 cm from the centre. What must the force of friction between the CD and the dirt be so that the bit of dirt continues to rotate in a circle and doesn't fly off? Give your answers in units of mN (millinewton), to three significant figures
