What is the potential energy at the end of the loop? what is the kinetic energy at the end of the loop (based upon the photogate time) I PUT THE TIME ON THE PICTURE? oh also can you help me find the speed of the car at the bottom of the hill like i know speed is distance multiples by time but i don’t know what number to use for distance.. the same picture shows some data i just don’t know how to use it. thanks would be greatly appreciated
