Question

Kylie has a mass of 54 kg and is jogging at a velocity of 3 m/s what is Kylie’s kinetic energy?

Answer 1

A :-) KE = 1 by 2 mv^2
Given - m = 54 kg
v = 3 m/s
Solution -
KE = 1 by 2 mv^2
KE = 1 by 2 x 54 x 3
( cut 2 and 54 because 2 x 27 = 54 )
KE = 27 x 3
KE = 81 J

.:. The kinetic energy is 81 joules.
