Suppose our experimenter repeats his experiment on a planet more massive than earth, where the acceleration due to gravity is g = 30~\rm m/s^2. when he releases the ball from chin height without giving it a push, how will the ball's behavior differ from its behavior on earth? ignore friction and air resistance. (select all that apply.)a. it will smash his face. b. it will stop well short of his face. c. it will take less time to return to the point from which it was released. d. its mass will be greater. e. it will take more time to return to the point from which it was released.

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)
