find the work done by a 45 N force in pulling the suitcase at an angle of 50 degrees with respect to the horizontal for a distance of 75m.

A horizontal force of 150 N is used to push a 40.0-kg packing crate a distance of 6.00 m on a rough horizontal surface. If the crate moves at constant speed, find (a) the work done by the150-N force and (b) the coefficient ofkinetic friction between the crate and surface.

24. (a) An object is pushed a distance 3.20 m along a frictionless horizontal table by a constant applied force of magnitude = 26.0 N directed at an angle of 25.0° below the horizontal as shown in Figure. If the mass (m) of the object is 2.50 kg calculate the work done by the applied force and power if it takes 2 minutes. d Answer: (i) The Work done by the applied force = J and (1) Power = W

An elevator having a mass of 585 kg is raised a distance of 32 m. Determine the work done, neglecting frictional effects and the work required for acceleration.

Calculate the work done on a 1500-kg elevator car by its cable to lift it 50.0 m up at constant speed, assuming friction averages 100 N.
