Physics Help please
77.
A 40.0-kg girl rides her 0.50-kg skateboard. She starts from rest and at a constant acceleration reaches 3.0 m/s in 10 s on a horizontal surface. How much power did she use?
I have no idea how to tackle this problem.

What formula should I use? My teacher sucks... we never got a formula sheet.
