Question

6.Two cars with different masses travel at the same speed down a hill toward a stop sign. What will happen when both cars apply brakes at the same time to stop? *

A. The car with the smaller mass will require less force to stop than the car with the larger mass.
B. The car with the larger mass will maintain its velocity while traveling down the hill.
C. The car with the smaller mass will take longer to stop than the car with the larger mass.
D. The car with the larger mass will have less inertia than the car with the smaller mass.****

Answer 1

F = m A
if they both started at the same speed and
if they both stopped at the sign
then they both had the same acceleration magnitude
one had a big m and the other a small m
so
which had the bigger F ?

Answer 2

is it A?

Answer 3

Yes

Answer 4

Maybe it's A
