Question 1150442: a ball is thrown from an initial height of 1 meter with an initial upward velocity of 15 m/s. The balls height h (in meters) after t seconds is given by the following.
h=1+15t-5t^2
find all values of t for which the balls height is 6 meters.
round answer to nearest hundredth.
if someone could help provide answer
