3. A race car starts from rest and accelerates at 8.1 m/s square. How far will it travel after 13 seconds? * 5
(1 Point)

For this question, we should apply
s = ut + 1 by 2 at^2
Given - u = 0
t = 13 secs
a = 8.1 m/s^2
Answer :-)
s = ut + 1 by 2 at^2
s = 0 x 13 + 1 by 2 x 8.1 x 13 x 13
s = 0 + 1 by 2 x 8.1 x 169
s = 0 + 1 by 2 x 1368.9
( cut 2 and 1368.9 by 674.45 because :
2 x 684.45 = 1368.9 )
s = 0 + 1 x 1368.9
s = 1 x 1368.9
s = 1368.9 m

Therefore , the car travelled
1368.9 meters after 13 seconds
