Pleaseee helppp asappp Mr. Smith decided to have another group of students run some foot races to figure out who had the most kinetic energy. A student with a mass of 49 kg was able to reach a velocity of 5.8 m/s. What was their kinetic energy if they ran on a raised track 5 m off the ground?

A second student was also racing. They were able to generate 815 J of kinetic energy. They had a mass of 52 kg. What was the final speed they were able to reach?​
