                     KE = 0.5*m*v2
KE = (0.5) * (625 kg) * (18.3 m/s)2

KE = 1.05 x105 Joules

             KE = 0.5*m*v2

KE = 0.5*625 kg*(36.6 m/s)2

KE = 4.19 x 105 Joules

Missy Diwater, 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?
              KE = 0.5*m*v2
12 000 J = (0.5) * (40 kg) * v2

300 J = (0.5) * v2

600 J = v2

v = 24.5 m/s
