What is the KE of a 72kg sprinter traveling at 12m/s?
Given: m= 72kg
            V= 12m/s
Required: KE
Formula: KE= 0.5 (m)(v)^2= mv^2
                                                 2
Solution: 0.5 (72kg) (12m/s)
                = 432^2
.                     2
                = 93312 J ~ final answer
