Under the action of a force, the modulus of which is F = 20H, the body moved horizontally at a distance s = 10m

Under the action of a force, the modulus of which is F = 20H, the body moved horizontally at a distance s = 10m. The force is directed at an angle of a = 60 ° to the horizon. Define power-perfect work.

With a rectilinear movement of a body in a horizontal plane, the work of the acting force is equal to:
A = F * S * cos (F, S), where F is the applied force (F = 20 N), S is the movement of the body (S = 10 m), cos (F, S) is the angle at which the force is applied to body (cos (F, S) = cos 60º).
Let’s calculate the work done by force:
A = F * S * cos (F, S) = 20 * 10 * cos 60º = 20 * 10 * 0.5 = 100 J.
Answer: The work done by force is 100 J.
