An athlete swings a 3.30-kg ball horizontally on the end of a rope. The ball moves in a circle of radius 0.880 m at an angular speed of 0.610 rev/s. (a) What is the tangential speed of the ball? m/s (b) What is its centripetal acceleration? m/s² (c) If the maximum tension the rope can withstand before breaking is 91 N, what is the maximum tangential speed the ball can have? m/s

An athlete swings a 6.30-kg ball horizontally on the end of a rope. The ball moves in a circle of radius 0.690 m at an angular speed of 0.450 rev/s. What is the tangential speed of the ball? What is its centripetal acceleration? If the maximum tension the rope can withstand before breaking is 128 N, what is the maximum tangential speed the ball can have?

How large is the centripetal force from friction and gravity? If this force is equal to force needed to maintain the automobile circular motion, what is the auto's maximum tangential speed?

An ultracentrifuge accelerates from rest to 8 X 104 rpm in 3.5min. What is the tangential acceleration of a point 0.08m from the center?

How do I find the tangential speed of a ball going in uniform circular motion, in the problem I'm working on, a 1.3 m long string makes a 48.8 degree angle below the hoizontal. I am confused as to how I find the w to plug into the Vt=rw equation to get the tangential speed. Thanks for your help!

Riders are seated in a horizontal circle of radius 7.50 m on a carnival ride. They start from rest and accelerate uniformly for 21.0 seconds to a maximum rotational speed of 1.40 rad/s. Calculate the tangential acceleration of the riders during the first 21.0 s of the ride.

1) An ultracentrifuge accelerates from rest to 100,000 rpm in 2.00 min. (a)What is the average angular acceleration in rad/s²? (b) What is the tangential acceleration of a point 9.50 cm from the axis of rotation? (c) What is the centripetal acceleration in m/s² and multiples of g of this point at full rpm? (d) What is the total distance traveled during the acceleration by a point 9.5 cm from the axis of rotation of the ultracentrifuge?

A floppy disk rotates with a constant angular speed of 56.4 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 4.54 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
