One common application of conservation of energy in mechanics is to determine the speed of an object. although the simulation doesn’t give the skater's speed, you can calculate it because the skater's kinetic energy is known at any location on the track. consider again the case where the skater starts 7 m above the ground and skates down the track. what is the skater's speed when the skater is at the bottom of the track? express your answer numerically in meters per second to two significant figures.
