An emergency worker applies a force to push a patient horizontally for 2.44m on a gurney with nearly frictionless wheels. Determine the work done in pushing the gurney if the force applied is horizontal and of magnitude of 15.5N. Determine the work done if the force, of magnitude 15.5N, is applied at an angle of 25.3° below the horizontal.
