Answers KE = 0.5 • m • v2 1. Determine the kinetic energy of a 625-kg roller coaster car that is moving with a speed of 18.3 m/s. Answer: KE = 0.5*m*v2KE = (0.5) * (625 kg) * (18.3 m/s)2 KE = 1.05 x105 Joules Missy Water, the former platform diver for the Ringling Brother's Circus, had a kinetic energy of 12 000 J just prior to hitting the bucket of water. If Missy's mass is 40 kg, then what is her speed? Answer  KE = 0.5*m*v212 000 J = (0.5) * (40 kg) * v2 300 J = (0.5) * v2 600 J = v2 v = 24.5 m/s

Answers Velocity = Distance/Time
