Question

A different car in the next lane accelerates from rest to 30 m/s at a rate of 6 m/s^2 for 5 seconds. How far does this car travel during this period?

Answer 1

You can use equation 4 for this:

$\left(30\,\dfrac{\mathrm m}{\mathrm s}\right)^2=0^2+2\left(6\,\dfrac{\mathrm m}{\mathrm s^2}\right)\Delta x$

$\implies\Delta x=75\,\mathrm m$
