You have water in a 10cm tall cylindrical can with a hole in it at the bottom. The flow from a hole depends on the water pressure, which is proportional to the height of the water above that hole: when water is W cm above a hole, then the flow from that hole will decrease the water height at a rate of 0.1*W cm/sec.

Write the function hprime = can1(t, h) that models the flow, then call ode45(@can1, [0 60], 10); to plot the water height over 60 secs starting full (10cm) . At roughly what time is there 1cm left?
