Question

A motorcycle is travelling along a straight road at 8 m/s.It accelerates at 1 m/s^2 for a distance of 18 m.How fast is it travelling ?Also calculate the time it has taken to cover 18 m.

Answer 1

Answer:

Explanation:from formula of motion

V²-U²=2as

V²-64m²/s²=2*1m/s²*18m

V=10m/s

We also know that

V=u+at

10m/s=8m/s+1m/s²*t

t=2s
