What was the total distance Mighty Mouse ha flown when he was finally smashed into mouse-mush by the cannonball?

**Steve**, Wednesday, April 24, 2013 at 2:01pmthe height of the ball is

h(t) = 134t - 9.8t^2

since 300 mph = 134m/s

so, when is the cannon ball back down? when h=0

t = 13.67 sec

so, how far does Mickey fly in that time (less 1 second), at 600 mph?

h(t) = 134t - 4.9t^2

so solve that for the correct time involved.
