A 0.08 kg bullet traveling at speed hits a 16.1 kg block of wood and stays in the wood. The block with the bullet imbedded in it moves forward with a velocity of 8.1 m/s. What was the velocity (speed) of the bullet immediately before it hit the block (in m/s)

Excuse ! extra points plus ! super desperate ! the position of an object does not move relative to a reference point. relative to the reference point the object _. a.) is not moving. b.) is moving.

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)

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes
