Question: 1. A bicycle wheel turns 25p rad during 45 s. Find the angular velocity of the wheel. 2. A lawn tractor tire turns at 65.0

1. A bicycle wheel turns 25p rad during 45 s. Find the angular velocity of the wheel.

2. A lawn tractor tire turns at 65.0 rpm and has a radius of 13.0 cm. Find the linear speed of the tractor in m/s.

3. A model plane pulls into a tight curve of a radius of 25.0 m. The 300-g plane is traveling at 90.0 km/h. What is the plane’s centripetal force?

4. A 0.950-kg mass is spun in a circle on a string of radius 60.0 cm. If its centripetal force is 12.0 N, at what velocity does it travel?

5. A girl riding her bike creates a torque of 1.20 lb ft with an angular speed of 45.0 rpm. How much power does she produce?
