3. A boat's speedometer reads 13m/s as it attempts to travel across the river that is 45m wide. A current of 4m/s is pulling the boat downstream. a. How long does it take for the boat to reach the other side of the river? b. If the dock on the landing the boat is trying to reach is 16m downstream, will the boat perfectly land at the dock, undershoot or overshoot the dock? Show work and explain below. c. At what angle does the boat make with respect to the river width?

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.
