Power and velocity physics homework

Homework Statement

What is the power needed to change the speed of a 1600 kg SUV from 15.0 m/s to 40.0 m/s in 4.0 seconds

The Attempt at a Solution

I know that P = W/t and W = F/d, but I feel like there is not enough info to use this equation. Am I missing something?

Can you calculate the change in the SUV's kinetic energy?

 

[ajmCane22]

Oh! So I would use $$\Delta$$K = 1/2m(Vf^2-Vi^2)?

 

[ideasrule]

Yes, that's the change in energy.
