Given,  

Force, F = 100 N  

Mass of the body, m = 20 kg  

Therefore, Acceleration is given by,  

Acceleration, a = F/m = 100/20 5m/s^2  

Now, Initial velocity, u = 0  

Final velocity, v = 100 m/s  

Acceleration, a = 5m/s^2  

Therefore, Time for which the force is applied,  

t = v-u/a = 100 - 0/5  

= 20s

Answer: 6 sec

Explanation:

F = ma

F= m(v-u) /t

100= 20(50-20) /t

100t= 20×30

100t = 600

t = 6 sec
