A body of mass 5kg is acted upon by a variable force. The force varies with the distance covered by the body. Find the kinetic energy (in Joule) of the body when the body has covered 30m distance? Assume that the body starts from rest.
    Correct answer is '295'. Can you explain this answer?
    Verified Answer
    A body of mass 5kgis acted upon by a variable force. The force varies ...
    Work done by force when body has covered 25m
    Area under curve upto distance 25m 
    Area between  25m to 30m is 
    So total work done by variable force till 30m is 250+45 = 295Joule
    So, change in kinetic energy = 295J.
    So final energy  = 295J.
    The correct answer is: 295
