Answer 2

Calculation of Work Done by a Force

To calculate the work done by a force, we can use the formula:

Work (A) = Force (F) × Distance (S) × cos(θ)

Where: - Force (F) is the magnitude of the force applied, which is given as 50 H. - Distance (S) is the distance over which the force is applied, which is given as 20 m. - θ is the angle between the direction of the force and the direction of displacement. Since the direction of the force and displacement are not specified, we will assume they are in the same direction, resulting in θ = 0.

Substituting the given values into the formula, we have:

A = 50 H × 20 m × cos(0)

Since cos(0) = 1, the equation simplifies to:

A = 50 H × 20 m × 1

Calculating the value, we get:

A = 1000 H·m

Therefore, the work done by the force is 1000 H·m.
