Question

A car is travelling along the road at 8m/s. It accelerates at 1m/square for distance of 18m. How fast is it travelling

Answer 1

Solution:-
It's given that,
u=8
a=1
s=18
By using equation=
${v}^{2} = {u}^{2} + 2as$
${v}^{2} = 8 \times 8 + 2 \times 1 \times 18 \\ {v}^{2} = 100 \\ {v}^{2} = {10}^{2} \\ v = 10$
Hence,
The answer is 10m/s
