P=Fd/t or P= change in energy/t
The Attempt at a Solution
i don't actually know where to start... i know i need to find the force he used, but i only know how to do that using friction, which i don't have i also don't have his mass. it would also be really helpful if someone could tell me how i need use the information "assuming the acceleration was constant"
