Answer:
work done by applied force is 800joule.
work done by gravitational force is 0
Step-by-step explanation:
(a) work done by applied force=Force×displacement=80×10=800
(b)since no gravitational force acts on the body so work done by gravitational force is 0
acceleration of the body=force/mass
=800/2=40m/s^2
