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 ms-२ ?
Step 1 of 2 Using , F = ma Step 2 of 2 Substituting the value of mass and acceleration in equation (i) F = mα m = 1500kg, α = 1.7ms⁻² F = 1500 x (-1.7) F = -2550 Newton Final answer Force between vehicle and road is -2550 Newton, here value of force is negative because it is acting opposite to the direction of motion.
