An automobile vehicle has a mass of 1,500 kg. What must be the force between the vehicle and road if the vehicle is to be stopped with a negative acceleration of 1.7 ms^–2?

Solution

Here,
Mass of the vehicle, m = 1500 kg
Acceleration, a = -1.7 ms^-2Force, F = ma = 1500 x (-1.7) = - 2,550N

The force between the vehicle and the road is 2,550 N.
The negative sign implies thatforce is acting in a direction opposite to the direction of the vehicle.
