Assuming that a vehicle slides to a stop without brake or tire failure, which of the following is NOT true?
A. A heavy truck will require more room to stop than an economy car
B. The number of wheels on a vehicle does not change the time needed to stop it
C. Acceleration is constant until the vehicle stops.
D. A greater kinetic coefficient of friction means a shorter stopping time
Why is the answer A? If it's a bigger car, won't it take longer to come to rest because it has more inertia?
