In order to complete a tough “split” in bowling, a bowling ball of mass 6.5 KG is rolled with a velocity of 12 M/S. The ball hits a 1.3 KG bowling pin, sending it off with the speed of 3.5 M/S at an angle of 80° with respect to the original direction of the bowling ball. What is the angle and direction of the bowling balls velocity after the collision with the pin?

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)
