A 500 kg go-cart is traveling at 15 m/s when the driver slams on the brakes. The cart comes to a stop in 7 m. If the same braking force is applied, how far will the cart travel after braking if it were traveling at 32 m/s?
a=(V^2-Vo^2)/2d=(0-15^2)/14=-16.07 m/s^2
d = (V^2-Vo^2)/2a
d = (0-(32^2))/-32.14 = 31.86 m.
