During an ice show, a 60.0-kg skater leaps into the air and is caught by an initially stationary 75.0-kg skater. (a) What is their final velocity assuming negligible friction and that the 60.0-kg skater's original horizontal velocity is 4.00 m/s? (b) How much kinetic energy is lost? Ans= a) 1.78 m/s b) -267J

If can, Calculate momentum Use the momentum impulse theorem, Analyze collisions using conservation of momentum, Calculate torques, and Apply Newton's Second Law for rotation
