An automobile vehicle has a mass of 1500 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 m s^-2?

Given,

Mass of vehicle, m = 1500 kg

Acceleration, a = - 1.7 m/s²

We know that,

Force, F = m × a

F = 1500 × (-1.7)

F = - 2550 N

Here, the negative sign shows that the force acts in a direction opposite to the direction of motion.
