You are spinning a bucket full of water (mass = 2 kg) by a rope (of L = 1 m) in a vertical circle. a. What is the minimum speed at which you can swing the bucket without getting wet?
b. The rope will provide up to 200 N of force before it breaks. What is the maximum speed at which you can swing the bucket?
c. If the rope does snap when the bucket is at its lowest point, in which direction does the bucket fly? Assume that you started spinning the bucket like you would an underhanded throw.

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
