In order to find the traction force, it is necessary to write down the general formula for the force:
F = ma,
where m is body weight,
a – its acceleration.
This force is equal in modulus to the traction force:
Fт = F = ma.
Let’s write down the formula for finding the amount of acceleration of the car:
a = (u – u0) / t = Δu / t.
Let’s substitute the value of acceleration in the formula for the thrust force:
Fт = ma = mΔu / t.
Let’s calculate the value of the traction force:
Ft = 4000 * 10/10 = 4000 N.
Answer: 4000 N.
