Question #59bfc

Answer 1

I found `1.3m/s^2`

Explanation:

We assume she starts from rest at `0km/h` so that after¨`6 s` she is at:
`27/3.6=7.5m/s` (I changed it to be consistent with the time).
Let us use kinematic in:
`v_f=v_i+at`
using our initial and final velocities we have:
`7.5=0+6a`
and rearranging:
`a=7.5/6=1.25~~1.3m/s^2`
