If you are running 5mph relative to the ground and you throw a ball 60mph relative to yourself in the direction you are running, then the ball is traveling at 65mph relative to the ground. You can determine this by simply adding the two speeds together, assuming that the ball is thrown in the direction you are running.
You can use the formula for kinetic energy (1/2 x mass x velocity squared). However, I don't know how efficient those brakes are; that is, how much percent of the energy typically gets recovered.
It would take approximately 13 minutes to travel 13 miles at a speed of 60 miles per hour.
Double the speed yeilds double the impact force.
When the speed of a car doubles, the force of impact quadruples due to the relationship between force and kinetic energy (which increases with the square of velocity). This means that a car traveling at 60mph will experience roughly four times the force of impact compared to when it is traveling at 30mph.
A catapult does not necessarily have to be big for it to go far. There are certain factors that affect how far a catapult will shoot. The speed of shooting and the force applied are the main factors.
