An electric fan is rotating at a constant 72,000 meters per hour, making one complete rotation in 0.17 seconds. (a) What is the magnitude of the speed of the bug sitting on one of fan's blades? (b) What is the magnitude of the acceleration of the bug sitting on one of fan's blades?

A ball travels in uniform circular motion with a Period of 2 seconds. What is the tangential velocity of the object if it is moving in a circle of radius 2 m? 2π m/s m/s 4π m/s 2 m/s 4 m/s

A small object of mass 0.500 kg is attached by a 0.870 m- long cord to a pin set into the surface of a frictionless table top. The object moves in a circle on the horizontal surface with a speed of 7.85 m/s. What is the magnitude of the radial acceleration of the object? Was given an answer of 70.83 but it’s wrong.

Now we have a rod-shaped space station of length 1296 m and mass 1.43 x 10^6 kg, which can change its length (kind of like an old-fashioned telescope), without changing its overall mass. Suppose that the station is initially rotating at a constant rate of 1.83 rpm. If the length of the rod is reduced to 1.83 m, what will be the new rotation rate of the space station? 1. 3.01 rpm 6.27 rpm 3 3.76 rpm 4 9.41 rpm

A rocket powered car is set inside a circular track and ignited. Pressure sensors on the wall of the track measure the centripetal acceleration of the car as a function of time to be ac (t) = (9 m/s®) tª + (42 m/s*) t² + (49 m/s³) If the radius of the track is 2.28 m, what is the tangential acceleration of the rocket car at t = 6.76 s? tangential acceleration: m/s?

The Mars Global Surveyor orbits Mars at an average altitude of 380 km. The average radius of Mars is 3390 km. If it takes the spacecraft 1.95 hours to complete one orbit around the planet, what is it's tangential velocity in kilometers per hour?

a marshmallow is placed 3.9cm away from the center of a rotating microwave plate for 0.6 minutes. if the plate rotates at 6.5 rpm, what is the tangential acceleration in m/s/s?

A race car is traveling on a circular track with a radius of 100m at a constant speed of 55m/s.(a) What is the race car’s period, T?(b) What is the race car’s angular frequency, ω?(c) What is the race car’s centripetal acceleration, Ac?

A manufacturer of CD-ROM drives claims that the player can spin the disc as frequently as 1100 revolutions per minute. If spinning at this rate, what is the speed of the middle row of data on the disc; this row is located 2.8 cm from the center of the disc?

A compact disc is rotating on a CD player turntable at a frequency 3.98 revolutions per second. The outer radius of the compact disc is r = 6.0 centimeters (0.060 m). What is the speed of a point on the outer edge of the compact disc?
