A bicycle wheel slows down uniformly to rest over a ditance of 45 m becuase the bicyclist sees something int he road ahead. Initally, a point out of the outside of the wheel is traveling at 8.0 m/s, and the wheel is 68 cm in diamtere.
a) What is the wheels inital angular velocty?
b) How many revolutions does the wheel make before comming to a stop?
c) Whats the angular acceleration of the wheel?
d) How long did it take to stop?
A small, 10.0 g insect stand at one end of a thin uniform metal rod which is initially at rest on a frictionless horizontal table. What is the resulting angular speed of the rod
Consider a rectangular swimming pool of depth 2.7 m with a width and length of 13 m. What is the force exerted by the water on one of the sidewalls of the pool
Suppose you walk 3.97 m down a 30° incline while holding a 1.05 kg block. The 3.97 m distance is measured as a displacement along the incline; not as a vertical change in height. How much work do you do on the block as you walk down the incline.
