A ball is thrown into the air. The function h=10t-5t^2 can be used to find the height(h) of the ball in meters after t seconds. How long does it take for the ball to reach a height of 5 meters?
Answers: 1
can be used to find the height(h) of the ball in meters after t seconds.
![\Rightarrow\ 1=2t-t^2\ \ \[\text{divide both sides by 5}]\\\\\Rightarrow\ t^2-2t+1=0\\\\\Rightarrow(t-1)^2=0\\\\\Rightarrow (t-1)=0\\\\\Rightarrow t=1](/tpl/images/0855/2463/cd388.png)
