# What force must be applied to the free end of the rope thrown over the movable block

What force must be applied to the free end of the rope thrown over the movable block to lift a load weighing 40 kg, friction should be neglected.

Task data: m (mass of a given load) = 40 kg; lifting with a movable block, friction is not taken into account.

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

Since the given load is lifted with the help of a movable block, then a force equal to half of its weight must be applied to the free end of the taken rope: F = P / 2 = m * g / 2.

Let’s perform the calculation: F = 40 * 10/2 = 200 N.

Answer: A force of 200 N must be applied to the free end of the rope.
