A geosynchronous satellite orbits above the equator of Earth in a circular orbit, remaining in a fixed position with respect to observers on the ground. Therefore, the satellite's period of revolution must be equal to the period of rotation of the Earth. When calculations are made to launch a certain geosynchronous satellite and the satellite is launched, the satellite's orbital period is slightly larger than the rotational period of Earth. Which of the following could have caused the difference? A) The mass of the satellite was larger than what was used in the calculation.
B) The mass of the satellite was smaller than what was used in the calculation.
C) The altitude of the satellite was larger than predicted by the calculation.
D) The altitude of the satellite was smaller than predicted by the calculation.
E) The diameter of the satellite was larger than what was used in the calculation.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
