Question

A car is travelling along the road at 8 metre per second. it accelerates at 1 metre per
second square for a distance of 18 metre. how fast is it then travelling ?

Answer 1

Answer:

U=8m/s

a=1m/s²

s=18m

v²-u²=2as

v²=2as+u²

v²=2×1×18+8²

v²=36+64

v²=100

v=10m/s

The car is traveling at 10 m/s after 18 m.

Answer 2

1. u=8m/s,a=1m/s^2,s=18m,v=?
2. v^2-u^2=2as

v^2-64=2×1×18

v^2=36+64

v^2=100

v=10m/s
