Question

A car is travelling along the road at 8m/s. If accelaration is 1m/s for distance of 18m. How fast is it then travelling.

Answer 1

Answer:

Step-by-step explanation:

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

Every second 8m

So, duration=2.25sec

So, final velocity =1*2.25+8

=8+2.25

=10.25m/s
