Question

a constant power P is applied to a car starting from rest if V is the velocity of the car at time t then what will be the relation between v and t

Answer 1

Answer:

v ∞ √t

Explanation:

we know that,

P = W/t

= Fs/t

= Fv (s/t = v)

= mav (F=ma)

= mv²/t (a=v/t)

P/m = v²/t

p and m are constants

so,

v²/t = constant

v² ∞ t

v ∞ √t.
