Question

I have no idea what to do here.

"Is it possible that the car could have accelerated to 55mph within 268 meters if the car can only accelerate from 0 to 60 mph in 15 seconds?"

Answer 3

You need to convert \(mph\) to \(ms^{^-1}\).

\(1~mile\approx 1609.34~m\)

So,
\(Speed = \Large\frac{60\times1609.34}{3600}\normalsize=26.8~ms^{-1}\)

You can use \(s=\Large(\frac{v+u}{2})\normalsize t\) to get the distance it car travelled while accelerating from 0 to 60 mph.

\(s=\Large(\frac{26.8+0}{2})\normalsize 15\approx 201~m\)

So it's possible to accelerate to 55mph within 268 m.
