Under the action of a force of 50N, a trolley weighing 40 kg. moves with an acceleration of 0.1m / s2. Find the resistance force.

Initial data: F (force acting on the trolley) = 50 N; m (trolley weight) = 40 kg; a (the acceleration that the trolley acquired) = 0.1 m / s ^ 2.

The force of resistance to the movement of this trolley is determined from the ratio:

m * a = F – Fc., whence Fc. = F – m * a.

Let’s make a calculation:

Fc. = 50 – 40 * 0.1 = 46 N.

Answer: The force of resistance to the movement of this trolley is 46 N.
