    Answer:

    a. 75 joules

    b. 37.5 joules

    c. 0 joules

    Explanation:

    work is defined as the product of force times the distance moved in the direction of the force

    Given data

    force F= 15N

    distance S= 5m

    1. In the direction of the force

    force= 15*5\\force= 75 joules

         2. In the direction at 60 degrees to the direction of the force

    force= 15cos 60* 5\\force= 15*0.5*5\\force= 37.5 joules

          3.  At right angles to the force

    force= 15cos 90* 5\\force= 15*0*5\\force= 0 joules
