Question

A 60-kg cheetah reaches a speed of 30 m/s as it chases its prey.What is the kinetic energy of the cheetah?

Answer 1

Kinetic energy = 1/2mv^2
                          = (1/2)(60)(30^ 2)
                   KE = 27,000 Joules

*just a reminder when you are solving for kinetic energy you have to make sure that the mass is given in kg and the velocity is given in m/sec. 

hope this helps :)

Answer 2

The answer would be 27,000 Joules because (1/2) m v^2 =30*900 which equals 27,000 J
