Going down the hill, the sled with the boy slows down with an acceleration of 2m / s ^ 2

Going down the hill, the sled with the boy slows down with an acceleration of 2m / s ^ 2. Determine the magnitude of the braking force if the total weight of the boy and the sled is 45 kg.

These tasks: a (the acceleration with which the sled with the boy slows down) = 2 m / s2; m (the total weight of the boy and the sled) = 45 kg.

The magnitude of the braking force acting on the sled with the boy is determined by the formula: Ftorm = m * a.

Let’s calculate: Ftorm = 45 * 2 = 90 N.

Answer: A braking force of 90 N acted on the sled with the boy.
