A ball is thrown into the air and follows a parabolic path given by the relationship h=-t^2+10t where h is the height of the ball in metres after t seconds of flight.
Find the total time the ball was in flight.
Hey everyone, I have tried doing this question and got t = 0 or 10
But textbook says it is -5 or 15
All help will be appreciated! Thanks!
