Read each scenario and then answer the question. Scenario A: A ramp is used to lift a refrigerator a height of 12 m with a force of 110 N. The ramp is at an angle of 50° to the ground.

Scenario B: A ramp is used to lift a refrigerator a height of 13 m with a force of 120 N. The ramp is at an angle of 22° to the ground.

Scenario C: A ramp is used to lift a refrigerator a height of 14 m with a force of 93 N. The ramp is at an angle of 34° to the ground.

Which scenario requires the most work?

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)
