Question

A car accelerates form rest uniformly at 3m/s. What is its velocity after travelling a distance of 24m?​

Answer 1

Your answer

V2 = U2 x 2ax

V2 = 0 x 2(3)(24)

V2 = 144

V = (sqrt{144})

V = 12ms-1

Answer 2

Answer:

12m/s

Explanation:

a = 3 m/s^2

Vi = 0

d = 24 m

d = (1/2) a t^2

24 = (1/2)(3)t^2

t^2 = 48/3 = 16

t = 4 seconds

v = Vi + a t

v = 0 + 3 (4)

v = 12 m/s
