In aviation, a "standard turn" for a level flight of a propeller-type plane is one in which the plane

makes a complete circular turn in 2.00 minutes. If the speed of the plane is 170 m/s,What is the radius of the circle?

In aviation, a "standard turn" for a level flight of a propeller-type plane is one in which the plane

makes a complete circular turn in 2.00 minutes. If the speed of the plane is 170 m/s, What is the centripetal acceleration of the plane?

A fly of mass 2.00 g is sunning itself on a phonograph turntable at a location that is 4.00 cm from

the center. When the turntable is turned on and rotates at 45.0 rev/min, calculate the centripetal

force needed to keep the fly from slipping?

4. The earth orbits the sun in 365 days. What is the tangential speed, in m/s, of the earth in orbit?

The average sun earth distance is 1.50 × 10 11 m.

A 900 kg race car makes one lap around a track of radius 50. m in 11.0 s. What is the car’s average speed?

A 900 kg race car makes one lap around a track of radius 50. m in 11.0 s. What is the car’s centripetal acceleration?

A speed skater goes around a turn with a 31 m radius. The skater has a speed of 14m/s and experiences a

centripetal force of 460N. What is the mass of the skater?

Norman Neutron swings a rubber ball attached to a string over his head in a horizontal, circular path. The

piece of string is 1.5 m long and the ball makes 120 complete turns each minute. What is the ball’s centripetal acceleration?

A penny, placed on a spinning record, rotates at 33 1/3 revolutions per minute when it is placed 10 cm

from the center of the record (mass of penny = 2.5 grams). What is the magnitude of the centripetal force necessary to keep the penny moving in a circular path?

A Ferris wheel with a 38 m radius and tangential speed of 5.0 m/s has a 76 kg passenger riding it. What is the magnitude of the centripetal force acting on the Ferris wheel passenger at the top and at the

bottom?
