Question

A car accelerates uniformly from rest at 3m/s(square).What is its velocity after travelling a distance of 24m?

Answer 1

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

Answer 2

U_3ms-1
-a=24m
t=?
V=0
V=u+at
O=3+(-24t)
0_3=-24t
-3\1=-24t/1 =8s
