Question

1. Car A has a mass of 8,000 Kg and is traveling at 40 miles per hour. Car B has a mass of 10,000 Kg and is traveling at 40 miles per hour. Which car has more kinetic energy?

Answer 1

car B

Step-by-step explanation:

K.E=1/2mv(squared)

K.E=1/2x10000x40x40

K.E=5000x1600

K.E=8000000J

convert to KJ

K.E=8000000/1000

K.E=8000KJ
