An automobile vehicle has a mass of 1500 kg. What must be the force between the vehicle and the road if the vehicle is to be stopped with a negative acceleration of 1.7 ms–2?
According to question
Mass of vehicle, m = 1500 kg
Acceleration a = 1.7 ms–2
∴ F = ma
F = 1500 × (–1.7)
F = –2550 N
The force of 2550 N, in the opposite direction of motion of vehicle.
