Lynne jogs daily around a circular track of diameter 25m for a total distance of 942 m in 5.0 min (a) how many times did Lynne jog around the track? (b) what is Lynne's average angular speed in radians/s?

The crankshaft in a race car goes from rest to 3000 rpm in 2.0 seconds. How many revolutions does it make while reaching 3000 rpm?

Human centrifuges are used to train military pilots and astronauts in preparation for high-g maneuvers. A trained, fit person wearing a g- suit can withstand accelerations up to about 9g (88.2 m/s2) without losing consciousness. HINT (a) If a human centrifuge has a radius of 5.17 m, what angular speed (in rad/s) results in a centripetal acceleration of 9g? X rad/s (b) What linear speed (in m/s) would a person in the centrifuge have at this acceleration? m/s

Human centrifuges are used to train military pilots and astronauts in preparation for high-g maneuvers. A trained, fit person wearing a g-suit can withstand accelerations up to about 9g (88.2 m/s2) without losing consciousness. (A) If a human centrifuge has a radius of 4.29 m, what angular speed (in rad/s) results in a centripetal acceleration of 9g? rad/s ?   (B) What linear speed (in m/s) would a person in the centrifuge have at this acceleration? m/s

Starting from rest, a wheel with a radius of 0.55 m begins to roll across the ground in a straight line under a constant angular acceleration of 4.05 rad/s2. What is the speed of the wheel in m/s after it has rotated through 17 full revolutions

A pulley having a 5.0-cm radius is turning at 30 rev/s about its central axis. It is slowed down uniformly to 20 rev/s in 2.0 s. Calculate the angular acceleration of the pulley, the angle through which it turns in this time, the length of belt it winds in that same time.

A child sits on a merry-go-round that has a diameter of 4.00 m. The child uses her legs to push the merry-go-round, making it go from rest to an angular speed of 17.0 rpm in a time of 43.0 s. What is the average angular acceleration aavg of the merry-go-round in units of radians per second squared (rad/s?)? davg = rad/s2 What is the angular displacement Að of the merry-go-round, in units of radians (rad), during the time the child pushes the merry-go-round?

A wheel of a radius 5.02 m rotates at a uniform speed. If a point on the rim of the wheel has a centripetal acceleration of 4.00 m/s2, what is the point’s tangential speed?

An airplane engine starts from rest; and 2 seconds later, it is rotating with an angular speed of 420 rev/min. If the angular acceleration is constant, how many revolutions does the propeller undergo during this time?

At t = 0s a grinding wheel has an angular velocity of 24.0 rad/s. It has a constant angular acceleration of 30.0 rad/s2 until a circuit breaker trips at t = 2.3 s. From then on it coasts to a stop over the next 10.0 seconds at constant angular acceleration. Through what total angle did the grinding wheel rotate? (Give your answer in radians.)
