Question

A car is travelling along the road at 8 M per second it accelerates at 1 m per second square for a distance of 18 M how fast is it them travelling?

Answer 1

u=8m/s.
a=1m/s².
s= 18m.

Using the third equation of motion we can find v.

2as=v²-u².
2(1)(18)=v²-64.
36=v²-64.
36+64=v².
100=v².
√100= v.
10=v.
v=10m/s.
