Answer:
Explanation:
here power = constant (power = work / time )
work / time = constant
f.s/t=constant ( work = f.s) ( force . displacement)
m.a.s/t= constant ( force = m.a) (mass . acceleration )
m. v/t . s=constant ( acceleration = v/t) ( velocity / time )
m.v.s/t^2
m.s/t.s ms^2 (v = s/t)
------------ = ----------- = (s^2 =t^3 constant ) = s is directly proportional to t ^ 3/2
t^2 t^3
