Given:-
- Mass of the vehicle (m) = 1700 kg
- Acceleration (a) = - 1.5 m/s² (At the direction of motion)
To Find: Force between the vehicle and the road if the vehicle is to be stopped at the given acceleration.
We know,
F = ma
where,
- F = Force,
- a = Acceleration &
- m = Mass.
∴ F = (1700 kg)(- 1.5 kg m/s²)
⇢ F = - 2550 kg m/s²
⇢ F = - 2550 N
☞ If we have to stop the vehicle at the given rate of change of velocity, then we need 2550 N force opposing the motion of the vehicle.
