MY answer is off by an annoying 0.01. The correct answer is 1m/s. Mine is 1.01m/s.

My "h" for 5s is 30.176. For 5.001, h is 30.177m

i too get 1.0115, the "correct answer" is prob due to rounding dh/dt = (20pi/60)cos(Tpi/60) = (pi/3)cos(Tpi/60) T = 5 dh/dt = (pi/3)cos(pi/12) = 1.0115

Wait. IT was the other way around. I worded that wrong.
