Select the correct location on the diagram.Devon ran a race on a flat track. He did not keep a constant speed during the race. The diagram below shows how fast he was running at different points on the track.At which point on the track did Devon have the most energy of motion?

Devin is watching two runners at the park. The runners are the same weight, and the speed that each of them is running is not changing.Devin wants to know which runner has the most energy of motion. What would he need to find out about the runners in order to determine this? A. the speed that they are running B. the direction that they are running C. the distance that they are running D. the location that they are running to

A train traveling at 4.0 m/s changes its speed to 2.0 m/s.Which graph shows the change in the kinetic energy of the train?

A race car track has been constructed with the a bank angle of 33.6° so there is no friction force. The race car track has a curve radius of 390. m. What speeds, for the race cars, has the track been designed to accommodate?

Breanne and Alison finished a 5 km fun run. Alison finished 400 m ahead of Breanne. Breanne ran at an average speed of 7.2 km/h.What was Alison’s time for the race if she ran at a constant rate for the whole race?
