1. 0.3       2. 0.5      3. 0.25      4. 0.1
ans: 0.25          Approach: take the diff and find out

Ans: mass
Approach:     power=work/time
hence numerator=(work*time)/time=work
work=Force*distance
Force=mass*acceleration
accelaration=distance/time^2
now numerator is (mass*distance^2) / (time^2)
denominator is (distance^2) / (time^2)       since velocity=distance/time
