Answer 1

Explanation:

█ Explanation █

✦ Use the equation y(t) = y₀ + v₀t + ½at² to find the time.

✦ Plug in the values of the equation.

✦ 620 = 225t - 4.9t²

✦ Reorder the equation to form it into the quadratic formula.

✦ 4.9t² - 225t + 620 = 0

✦ Solve for t

✦ t = 43

It will take 43 seconds for the shell above the ground.
