Determine the force of resistance to movement if a trolley with a mass of 1 t under the action

Determine the force of resistance to movement if a trolley with a mass of 1 t under the action of a traction force of 700N has acquired an acceleration of 0.2 m / s ^ 2

Problem data: m (mass of a given bogie) = 1 t (in SI m = 1 * 10 ^ 3 kg); F (acting pulling force) = 700 N; a (acceleration acquired by the trolley) = 0.2 m / s2.

To determine the required force of resistance to the movement of a given trolley, we project all the forces onto the ОХ axis: m * a = Fthrust – Fc., Whence Fc. = F draft – m * a.

Let’s make a calculation: Fcopr. = 700 – 1 * 10 ^ 3 * 0.2 = 500 N.

Answer: The required force of resistance to the movement of a given trolley is 500 N.
