Move on! Solve the problem and show the process on the space provided below. Suppose the height of an object fired straight up from ground level is given by s(t) = 200t - 4.9t2 where s is measured in meters and t is measured in seconds. a. How fast is the object moving as it leaves the ground after 2 seconds? b. How long will it take for the object to hit the ground? c. Find the velocity of the object when it hits the ground. Solution:
