Question

An automobile has a mass of 1500 kg. What must be the force between the vehicle and the road, if the vehicle is to be trapped with negative acceleration of 1.7 ms$^{–2}$​

Answer 1

Answer:

Given:-

Mass of automobile (m) = 1500 kg.

Acceleration (a) = –1.7 ms$^{–2}$

To find:-

Force between the vehicle and the road

Solution:-

We know that,

Force (f) = ma

= (1500 kg) (–1.7 ms)$^{–2}$

= –2550 N.

Thus, force between the vehicle and the road if the vehicle is to be stopped with a negative acceleration of 1.7 ms$^{–2}$ is –2550 N.
