# Rotational Kinematics and Energy!

Hello! I need help with the following the questions. Any hints are welcome. Thank you so much in advance!

1) A Ferris wheel with a radius of 14.0 m rotates at a constant rate, completing one revolution in 30.0
s. What is the apparent weight of a 60.0-kg passenger when she is at the bottom of the wheel?

2) A potterʹs wheel is rotating at 1.00 rpm. What centripetal force is required to hold a 1.00 g lump of
clay in place, 10.0 cm from the axis of rotation?
