Determine the force of resistance to movement if a trolley with a mass of 1.2 tons, under the action

Determine the force of resistance to movement if a trolley with a mass of 1.2 tons, under the action of a traction force of 600N, has acquired an acceleration of 0.2 m / s2.

Initial data: m (trolley weight) = 1.2 t; F (traction force, which imparts acceleration to the trolley) = 0.2 m / s ^ 2; a (the acceleration that the trolley acquired) = 0.2 m / s ^ 2.

SI system: m = 1.2 t = 1.2 * 10 ^ 3 kg.

The force of resistance to movement is determined using the following equality: m * a = Fthroat – Fcomp.

Fc. = F draft – m * a.

Let’s calculate: Fcopr. = 600 – 1.2 * 10 ^ 3 * 0.2 = 600 – 240 = 360 N.

Answer: The force of resistance to the movement of the trolley is 360 N.
