Question

Laura is a star runner of the school's track team. During a trial, her speed was measured to be 9.80 m/s. If Laura's mass is 45.2 kg, her kinetic

energy during the trial was

Answer 1

KE = 2.17 E3 J

Step-by-step explanation:

m = 45.2 kg

v = 9.8 m/s

KE = 1/2mv^2

KE = [(45.2 kg)(9.8m/s)^2]/2

KE = 2.17 E3 J
