Excited at the prospect of assisting some students with M3!

How to use SUVAT.  My friend jumps from a height of 85m, the bungee is taut at 80m – what is her maximum velocity?
Use v²=u²+2as.  u is initial velocity(zero obviously!!), a is acceleration(Newton discovered this, use 10m/s²) and assume no air resistance.  Now all you have to do is convert to something meaningful like Km/hour or miles/hour.
