Answer:
We know
= -2550N
Hence -2550N is to be applied in the opposite direction to that of the vehicle's motion in order to stop

AnswEr :
⠀
- The force applied by the vehicle = 2550 N.
⠀
Explanation :
⠀
It is given that, the mass of a vehicle and the acceleration produced by the vehicle, that is,
⠀
- Mass of vehicle, m = 1500 kg.
⠀
- Acceleration produced by vehicle, a = -1.7 m/s².
⠀
We are supposed to find the force applied bt the vehicle.
⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━
⠀
We will find the force applied by the vehicle by 2nd law of Newton.
⠀
By using the second law of Newton :
⠀
Where we have the values as :
- F = unknown.
- m = 1500 kg.
- a = -1.7 m/s².
⠀
Substituting all the given values :
⠀
The negative sign indicate that the direction of vehicle is opposite.
