Question

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−2 

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

This is a friction force.

Answer 2

⛄Aɳടɯҽɾ⛄

we know

➳Force = ma

➳Magnitude of force = 150 × 1.7 = 25507 N

➳F = 1500× ( -1.7 ) =

-2550 N ☑☑
