A projectile is launched from a platform, its trajectory can be approximated by the function h(t) = -16t^2 +62t+19 where h is the height in meters of the projectile and t is the number of seconds after the projectile is launched.

What height will the projectile be at 0.5 seconds?

What maximum height will it reach?

How much time will its take for the projectile to land?
