During an ice show, a 100.0-kg skater leaps with an initial of 4.00 m/s into the air and is caught by an initially stationary 75.0-kg skater. How much kinetic energy (KE) is lost (enter your energy in Joules)? Assume the friction force is negligible. (Hint: First find the final common velocity and subtract the final KE from the initial KE)
