Quadratics Projectile Motion

If the function h(t) = -16t² + 160t represents the relationship between the height "h" of an object "t" seconds after it is launched, how many seconds will it take for the object to reach it's maximum height?

The function h(t) = 125t - 5t² represents the height "h" of an object "t" seconds after it was launched into the air from the ground. How many seconds will it take for the object to hit the ground? Find the roots (Input only the number)
