Question

A girl starts her car and accelerates uniformly to 7m/s in a distance of 14m.Calculate the acceleration of the girl and the time taken by her to travel the distance​.

Answer 1

u = 0

v= 7m/s

s=14m

From the relation,

v²=u²+2as

47=0+2×a×14

a= 2×14/27

a=1.03703704

time taken

v=u+at

7=0+1.03703704×t

t=6.74999764s

Hope it helps
