The height (in meters) of a projectile shot vertically upward from a point 2 m above ground level with an initial velocity of 22.5 m/s is h = 2 + 22.5t − 4.9t2 after t seconds. (Round your answers to two decimal places.)(a) Find the velocity after 2 s and after 4 s. v(2) = m/sv(4) = m/s(b) When does the projectile reach its maximum height?s(c) What is the maximum height?m(d) When does it hit the ground?s(e) With what velocity does it hit the ground?m/s
