Lilyana Barker · Answer 1

Kinetic energy is KE=0.5mv^2

Since the car is mass is the smallest efor the three situations

the Kinetic energy at 30 mph

KE1=0.5 m (30) ^2

the Kinetic energy at 15 mph

KE2=0.5 m (15) ^2

the Kinetic energy at 0 mph

KE3=0

KE1>KE2

The Kinetic energy at 30 mph is the highest
