With the help of a movable block, he lifts a load weighing 20 kg. What force is applied to the free end of the rope.

These tasks: the taken load is lifted using a movable block; m (weight of cargo) = 20 kg.

Reference values: g (acceleration due to gravity) ≈ 10 m / s2.

The force that was applied to the free end of the rope to lift the taken load is calculated by the formula: F = P / 2 = m * g / 2.

Calculation: F = 20 * 10/2 = 100 N.

Answer: To lift the taken load, a force of 100 N was applied.
