Question

Q. A vehicle has a mass of 1500kg
What must be the force between
the vehicle and the road it the
schicle is to be stopped with a
negative acceleration of 1.7 ms
(ARS - 2550 N in a direction.
Opposite to that of the motion
of the vehicle)​

Answer 1

Answer:

Mass of vehicle = 1500kg

Retardation required = −1.7ms

Force between road and vehicle = 1500×−1.7=-2550 N

This is a friction force.

Answer 2

Answer:

Hence, the force between the automobile and the road is -2550 N, in the direction opposite to the motion of the automobile.
