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 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*v J = (0.5) * (40 kg) * v2
300 J = (0.5) * v2
600 J = v2
v = 24.5 m/s
