Q8 of 31 Page 128

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.
