17) What is the unit of the following? (power*time) / (velocity*velocity)
1.mass 2.distance 3.velocity 4.speed
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
