Question

A car starts with uniform acceleration along a straight road. After 15 seconds, the distance covered by the car is 450 m. The displacement of the car in 15th second

Answer 1

Explanation:

Distance =speed *time

450=s*15

450/15=speed

Speed or velocity =30m/s

Accl^n=velocity /time

a=30/15

a=2m/s^2

Therefore,, displacement =u+a/2(2t-1)

Displ. =30+(2*15-1)

Displ. =30+29

D=59m
