A 80.0 kg passenger is seated 12 m from the center of the loop of a roller coaster. What centripetal force does the passenger experience when the roller coaster reaches an angular speed of 3.14 rad/s?

A Lazy Susan (turning tabletop) has radius 0.750 m. An apple is placed at the edge of the turning table. A child turns the tabletop from rest to an angular speed of 5.00 rev/min in 3.00 s. What is the value of the apple's tangential acceleration at 3.00 second in m/s²? Your Answer: Answer A Question 26 (4 points) staks question A Lazy Susan (turning tabletop) has radius 0.750 m. An apple is placed at the edge of the turning table. A child turns the tabletop from rest to an angular speed of 5.00 rev/min in 3.00. What is the value of the apple's centripetal acceleration at the 3.00 second in m/s²?

On a carnival ride, you stand next to a wall of a circular drum which spins around the center. When drum is spinning fast enough the floor drops away and you remain stuck to the wall and do not slide down to the floor until the drum slows down some. Assume a rider has a mass of 55.0 kg, and the drum has a radius of 6.00 m. The average linear speed that a rider is traveling with around the drum is 7.80 m/s. What is the normal force that the drum is exerting on the rider to keep her from sliding down to the floor?

A 1.3 kg rock is swung in a circular path and in a vertical plane on a 1 m length string. At the top of the path, the angular velocity is 24 rad/s. What is the tension in the string at that point?

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?

A 83-kg pilot in training sits in a centrifuge that spins his seat around a central axis. When the seat is moving in its circular path at a speed of 3.0 m/s, he feels a 585-N force pressing against his back (the seat faces the axis). What is the radius of the centrifuge?

t has been suggested that rotating cylinders about 16.0 mi long and 5.06 mi in diameter be placed in space and used as colonies. What angular speed must such a cylinder have so that the centripetal acceleration at its surface equals the free-fall acceleration on Earth?

Starting from rest, a basketball rolls from the top to the bottom of a hill, reaching a translational speed of 6.3 m/s. What is the height of the hill?(Ignore frictional losses) 2.0 m 3.4 m 4.1 m 6.1 m

A turntable rotates at 45 rev/min. Calculate the angular velocity of the turntable. A particle on the turntable is located 0.13 m from the center of the rotating turntable. What is the speed of the particle? The particle on the turntable has a mass of 3 g. Calculate the force of friction which keeps it from sliding off.

An athlete swings a 4.20-kg ball horizontally on the end of a rope. The ball moves in a circle of radius 0.610 m at an angular speed of 0.690 rev/s. a.) What is the tangential speed of the ball?   (b) What is its centripetal acceleration?   (c) If the maximum tension the rope can withstand before breaking is 84 N, what is the maximum tangential speed the ball can have?
