Question

1)Determine the dimension of power if the formula for power is

power = force * velocity​

Answer 1

Answer:

Power formula in terms of force

The expression for power is work/time. And since the expression for work is force*displacement, the expression for power can be rewritten as (force*displacement)/time. Since the expression for velocity is displacement/time, the expression for power can be rewritten once more as force*velocity. This is shown below.

Answer 2

Answer:

Power=force×velocity

P=F×v

F=[MLT^−2]

v=[LT^−1]

Therefpre, the dimensional formula of power, P=[MLT^−2]×[LT^−1]

=[ML^2T^−3]
