In a DVD player, the centripetal acceleration is measured to be 200 m/s2, at a point that is 0.02 m from the center of the disc. What is the rotating speed of the DVD? What is the centripetal acceleration at a point that is 0.06 m from the center of the disc? Is the rotating speed of the DVD different at different radial locations?

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. The athlete is able to rotate the ball at the rate of 8.00 rev/s when the length of the chain is 6.600 m. When be increases the length to 0.900 m, he is able to rotate the ball only 6.00 rev/s. (a) Which rate of rotation gives the greater speed for the ball? (b) What is the centripetal acceleration of the ball at 8.00 rev/s? (c) What is the centripetal acceleration at 6.00 rev/s?
A door in a hospital has a pneumatic closer that pulls the door shut such that the doorknob moves with constant speed over most of its path. In this part of its motion, (a) does the doorknob experience a centripetal acceleration? (b) Does it experience a tangential acceleration?
A father fashions a swing for his children out of a long rope that he fastens to the limb of a tall tree. As one of the children swings from this rope that is 8.30 m long, his tangential speed at the bottom of the swing is 7.85 m/s. What is the centripetal acceleration, in m/s2, of the child at the bottom of the swing?
The circular blade of a table saw is 25 cm in diameter and spins at 3600 rpm. How much time is required for one revolution? How fast is one of the teeth at the edge of the blade moving? What is the tooth’s acceleration?
A fairground ride spins its occupants inside a flying saucer-shaped container. If the horizontal circular path the riders follow has a 4.8 m diameter, if the riders is subjected to a centripetal acceleration 1.3 times that due to gravity, what is the spinning speed in unit of revolutions per minute? Use g = 9.8 m/s2.
A runner taking part in the 200-m dash must run around the end of a track that has a circular arc with a radius of curvature of 30.0 m. The runner starts the race at a constant speed. If she completes the 200-m dash in 23.2 s and runs at constant speed throughout the race, what is her centripetal acceleration as she runs the curved portion of the track?
A fairground ride spins its occupants inside a flying saucer-shaped container.

Use g = 9.8 m/s2.
A skater starts the jump moving forward as shown, leaps into the air, and turns one-and-a-half revolutions before landing. The typical skater is in the air for about 0.5 s, and the skater’s hands are located about 0.8 m from the rotation axis. The skater’s arms are fully extended during the jump. What is the approximate centripetal acceleration of the skater’s hand?A. 10 m/s2 B. 30 m/s2 C. 300 m/s2 D. 450 m/s2
A runner taking part in the 200 m dash must run around the end of a track that has a circular arc with a radius of curvature of 35 m. The runner starts the race at a constant speed. If she completes the 200 m dash in 22.6 s and runs at constant speed throughout the race, what is the magnitude of her centripetal acceleration (in m/s2) as she runs the curved portion of the track?

chrt3pt #5 For safety reasons, a circular ride at an amusement park is limited to a centripetal acceleration of 0.500g. If the car farthest from the centre is 8.25 m from the centre, what is the period of rotation of the ride?#6 The top of a hill on a roller coaster has a circular shape with a radius of 25.0 m. A car going over the top makes the passengers feel weightless at the very top. How fast is the car going?
