The body moves along a horizontal surface under the action of a force of 20 N applied to the body

The body moves along a horizontal surface under the action of a force of 20 N applied to the body at an angle of 60 degrees to the horizontal. Determine the work of this force when the body moves 5 m.

To find the work of a given force when moving a body, we will use the formula: A = F * S * cosα.

Values of variables: F – acting force (F = 20 N); S – movement of the taken body (S = 5 m); α is the angle between the given force and displacement (α = 60º).

Calculation: A = F * S * cosα = 20 * 5 * cos 60º = 50 J.

Answer: When moving the taken body, a work of 50 J.
