Answer:
please follow me....
Step-by-step explanation:
Given, mass of the body, m=5kg;
Initial velocity of the body, u=0;
Force acting on the body, F=20N;
Time for which the force acts, t=10s
If a is the acceleration produced in the body,
a=
m
F
=
5
20
=4m/s

Let v be the velocity of the body after 10 s.
Clearly, v=u+at=0+(4)×(10)=40m/s
Kinetic energy acquired by the body,
E
