Do you ever wonder about the bullet holes in deer crossing (xing) signs? Perhaps the passenger of a car or truck had a gun on hand and decided to shoot signs while his/her friend drove. Suppose that the gun had been tested the previous week and found to shoot bullets at a speed of 1500 miles/hour. Suppose that the car/truck was going at a speed 65 miles an hour. Suppose that the passenger was shooting in the forward direction, at signs that were ahead of the car/truck. You can ignore air resistance. In the reference frame of the deer crossing sign, how fast was the bullet traveling when it hit the sign? In the reference frame of the shooter, how fast was the bullet traveling when it hit the deer crossing sign?
