Determine the acceleration with which the sleigh rolls down the mountain, if their mass is 45 kg

Determine the acceleration with which the sleigh rolls down the mountain, if their mass is 45 kg, and the pushing force on them is 900N.

Initial data: m (sled weight) = 45 kg; F (push force of the sled, the force applied to the sled) = 900 N.

If you do not take into account the resistance forces that act on the sled, then the acceleration of the sled can be expressed from the formula (Newton’s second law): F = m * a and m = F / a.

Let’s calculate: m = 900/45 = 20 m / s ^ 2.

Answer: The acceleration of the sled is 20 m / s ^ 2.
