A force of 25.0 N is applied to an object of mass 5.0 kg. The object covers a distance of 10.0 m. Calculate the work done when the direction of the applied force is same as the direction of motion. Calculate the amount of force required if the same amount of work is to be performed, when the force is applied at an angle of 30˚, 60˚, 75˚. Compare these values and comment on your observation.
