Two cars (one red, one blue) are both making a turn. Each vehicle has the same mass and turn radius but the red car is moving at twice the speed of the blue car. How do the centripetal forces acting on each vehicle compare?
Centripetal force is four times larger for the red car.
Centripetal force is two times larger for the red car.
Centripetal force is two times weaker for the blue car.
Centripetal forces are equal.

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)
