Imagine you are on an amusement park and on a train ride. At some point the train ride follows a horizontal circle of radius r = 5.00 m around a center “O”. At what magnitude of tangential velocity of the train carts do you have a centripetal acceleration with magnitude of 2.5g? g is the standard gravitational acceleration on the surface of theEarth.a. about 2.42 m/sb. about 123 m/sc. about 11.1 m/sd. about 19.8 m/s

Awind turbine is rotating counterclockwise at 0.75 rews and slows to a stop in 10s. Its blades are 15 m in length. What is the centripetal acceleration of the tip of the blades at t1s? (Round off answer to ONE decimal place) wrong 333.1

What would Earth’s rotational period haveto be for objects on the equator to have acentripetal acceleration of 9.8 m/s 2? AssumeEarth’s radius is 6,380 km.

A particle describes an arc of circumference of 6.6 m radius. At the instant in which the speed is v = 6.6 m / s and theta = 53 degrees celsius between the radius and the total acceleration. will have a tangential acceleration of?

A compact disc (CD) stores music in a codedpattern of tiny pits 10-7 m deep. The pits are arranged in a track thatspirals outward toward the rim of the disc; the inner and outer radii ofthis spiral are 25.0 mm and 58.0 mm, respectively. As the disc spinsinside a CD player, the track is scanned at a constant linear speed of1.25 m/s. (a) What is the angular speed of the CD when the innermostpart of the track is scanned? The outermost part of the track? (b) Themaximum playing time of a CD is 74.0 min. What would be the lengthof the track on such a maximum-duration CD if it were stretched outin a straight line? (c) What is the average angular acceleration of amaximum-duration CD during its 74.0 min playing time? Take the directionof rotation of the disc to be positive.

In an examination of a pediatric patient the operating console controls are set at 600 mA/30 ms. Whatis the mAs?

When a fan is turned off, its angular speed decreases from 168 rpm to 64.0 rpm in 6.08 s.  A) what is the angukar acceleration of the fan? B) How fast the edges of the blades are moving (in m/s) at time 6.08 s, if they are 86.0 cm long?
