Question

A 0.0296 kg ball is shot from the plunger of a pinball machine. Because of a centripetal force of 0.0485 N, the ball follows a circular arc whose radius is 0.309 m. What is the speed of the ball? A curve of radius 113 m is banked at an angle of 16.8 degree. At what speed can it be negotiated under icy conditions where friction is negligible? Two satellites, A and B, are in different circular orbits about the earth The orbital speed of satellite A is 6.29 times that of satellite B. Find the ratio of the period of satellite A to that of satellite B.

Explanation / Answer

According to the chegg guidelines I am allowed to answer only 1 question at a time.

1) m =0.0296 kg F =0.0485 N r = 0.309 m

V = sqrt ( F * r / m ) = sqrt ( 0.0485 N * 0.309 m / 0.0296 kg )

V = 0.711548083 m/s ======================ANSWER)
