A force of 40N acting at 60 to the horizontal pulls a block of mass 10kg a distance of 2.0m across a smooth surface. How much work is done?

Respuesta :

Answer: 40 J

Explanation:

The work done by a force can be calculated using the formula:

W = Fdcosθ, where:

  • W is the work done
  • F is the force applied
  • d is the distance over which the force is applied
  • θ is the angle between the force vector and the direction of displacement

In this case, F = 40N, d = 2m, and θ = 60°.

W = Fdcosθ

W = 40·2·cos(60°)

W = 40

Therefore the work done is 40 Joules.
