A bus is traveling at a speed of 20.0 m on a straight horizontal road. The wheels have a radius of 0.400 m. If the bus speeds up with a linear acceleration of 1.50 m/s2 for 8.00 s, what is the angular speed of each of the wheels during this time?

A floppy disk rotates with a constant angular speed of 60.6 rad/s. Find the tangential speed at a point 0.073 m from the axis of rotation. What is the magnitude of the centripetal acceleration at this point?

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

A ball of radius 0.200 m rolls with a constant linear speed of 2.47 m/s along a horizontal table. The ball rolls off the edge and falls a vertical distance of 2.20 m before hitting the floor. What is the angular displacement of the ball while the ball is in the air?

I need help on this question: You are driving on a horizontal circular road of radius 50.0 m at a constant speed of 11.17 m/s. How much time does it take to complete 10 rounds?What is your angular velocity? When you are at the northern most point on the road, what is the magnitude and direction of your acceleration?

A point on the rim of a 0.81 m radius rotating wheel has a centripetal acceleration of 6.9 m/s2. What is the angular velocity of a point 0.42 m from the center of the wheel?

The tires of a car make 85.0. revolutions as the car reduces its speed uniformly from 90.0 km/hr to 60.0 km/hr. The tires have a diameter of 0.90 m. What is the angular acceleration? If the car continues to slow down at this rate, how much more time is required to stop?

A ballerina with an angular velocity of 1000°/s with her left hip in 90° flexion and knee fully extended, meaning that her foot is directly in front of her body. The distance from her axis of rotation to her foot is 0.95m. What is tangential velocity of her foot as she spins (in m/s)?

An ultracentrifuge accelerates from rest to 109700 rpm in 2.05 min. ω = 109700 rpmt = 2.05 minl = 9.4 cma. What is its angular acceleration in rad/s2? α =b. What is the tangential acceleration of a point 9.4 cm from the axis of rotation in m/s2? at =c. What is the centripetal acceleration in multiples of g of this point at full speed? a/g =

When you start your record player, a ladybug is sitting on the edge of the record, 15 cm from the center. The record, initially at rest at t=0, experiences a constant angular acceleration of 0.698 rad/s for 5 seconds.  What is the magnitude of the centripetal acceleration of the ladybug at the moment t = 5 s?
