electric car help :)

A projected electric vehicle makes use of storage batteries as its source of energy. Its mass is 1560 kg and it is powered by 24 batteries, each 12 V, 95 A hr. Assume that the car is driven on level roads at an average speed of 32.4 km/hr and the average friction force is 240 N. Assume 100% efficiency and neglect energy used for acceleration. No energy is consumed when the vehicle is stopped, since the engine doesn’t need to idle. Determine the horsepower required.

You need to show what sorts of concepts you would use to solve this problem and an attempt at a solution before we can help. I will tell you that you don't need all of the information you are given. Which info is necessary and which isn't?

A simple force*velocity = power, converted into horsepower seems to work. seems I posted prematurely. Sorry for that :(
