    Pressure, volume and work done in an ideal

    I am having trouble with this question:( Any advice. One mole of an ideal gas at a pressure p0 and a volume V0 undergoes the following changes in order: (i) expands to twice its volume at a constant pressure (ii) heats to twice its initial pressure at constant volume (iii) is compressed to...

    Maximizing Velocity in Uniformly Accelerated Motion

    Yip, that done it...lol thanks a lot for your help, it has cheers me up after a freak out earlier. I think I've been looking into further than was needed. Thanks again, Jeff

    Maximizing Velocity in Uniformly Accelerated Motion

    Thanks for the quick reply. Yes I have looked at that but as I didnt have a velocity it seemed useless. I think I'm struggling as there is only 2 components to use i.e. time and total distance. I'll keep trying :) cheers

    Maximizing Velocity in Uniformly Accelerated Motion

    Homework Statement a car takes 3 mins to travel between 2 sets of traffic lights which are 1800m apart, its velocity at each set of lights is 0ms-1 If the car accelerated uniformly for 30 secs and then maintained a constant velocity for the next 2 mins before retarding uniformly, calculate...
