QUESTION 1 A boy takes a 2.0-kg rock and ties it to the end of a light, uniform, 0.80-m-long rope. He then grabs the other end of the rope and swings the rock in a vertical circle. If he imparts a tension of 20 N to the rope as he swings the rock over the top of the circular motion, what will be the speed of the rock at the very top of the motion? Assume that g = 9.8 m/s2. а. 2.0 m/s b. 6.0 m/s C. 5.0 m/s d. 4.0 m/s е. 3.0 m/s

A circus motorcycle acrobat is trying to calculate the speed required to perform a loop- the-loop with a motorcycle. The loop has a radius of 10 m. At what speed must the motorcycle enter the loop at the bottom to negotiate a complete loop against gravity, without the use of its engine while in the loop? We do not have enough information. Mass is required. b) More than 20 m/s. c) More than 25 m/s. Exactly 20 m/s. Exactly 25 m/s.
