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.

An astronaut with a mass of 75.8kg, finds herself 34.7m from her spaceship. The only way for her to return to the ship is to throw her 0.450kg wrench directly away from the ship. If she throws the wrench with a speed of 20.3m/s, how many seconds does it take her to reach the ship?

How would I begin to solve this problem? In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth. A better expression for a rocket's position measured from the center of the Earth is given by y(t) = (RE3/2 + 3*(g/2)1/2 REt)2/3 where RE is the radius of the Earth (6.38 ✕ 106 m) and g is the constant acceleration of an object in free fall near the Earth's surface (9.81 m/s2). (a) Derive expressions for vy(t) and ay(t). (Use the following as necessary: g, RE, and t. Do not substitute numerical values; use variables only.)
Determine the acceleration of gravity g using your (a) position versus time graph equation (b) velocity versus time graph equation. A Equation: y=-4.2238t^2-1.2466t+1.0791 B Equation: y=-8.152x-1.2934

Answer part C). If the blue object actually had an inital veloctiy of 50 m/s j, how long after the green projetile is launched should the blue object be launched if they are to collide? Let the blue object be traveling upward when they collide.
Deimos, a moon of Mars, is about 12 km in diameter with mass 2.0 × 10¹5 kg. Suppose you are stranded alone on Deimos and want to play a one-person game of baseball. You would be the pitcher, and you would be the batter! a. With what speed would you have to throw a baseball so that it would go into a circular orbit just above the surface and return to you so you could hit it? Do you think you could actually throw it at this speed? b. How long (in hours) after throwing the ball should you be ready to hit it? Would this be an action-packed baseball game?
