An arrow (m = 5.0 g) is fired at a styrofoam block (m = 150 g) sitting on the edge of a frictionless table. The tabletop is 1.1 m above ground. The arrow enters the block horizontally at va1 = 35 m/s and passes through to the other side, exiting horizontally at va2 = 15 m/s. a) Determine the speed of the styrofoam after the arrow exits the block. b) Determine where the Styrofoam will land with respect to the arrow. Assume the arrow passed right through the centre of mass of the block, and both objects drop the same vertical distance to the ground.

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
