How Much Power Does a 1500-kg Racecar Need to Reach 90 km/h in 5 Seconds?

[JustinKim]

Help Please!

A 1500-kg racecar can go 0 - 90 km/h in 5.0s. What average power is required to do this?

you shall be able to get the acceleration and so you can get the force and you can find the final velocity where the initial velocity is 0, then you know that P=FV, and its done. it's very simple.
