The International Space Agency has finally landed a robotic explorer on an extra-solar planet. Some probes are extended from the lander's body to conduct various tests. To demonstrate the crushing weight of gravity on this planet, the lander's camera is aimed at a probe's ground-level ejection port, and the port launches a baseball directly upwards with a path of h(t) = -49t2 +147t. Assuming no winds and that the probe can scurry out of the way in time, how long will it take for the ball to smack back into the surface and find the max height of the ball? Time is in seconds and height is in feet. (Hint: Graph the function)
What is the ball takes 3 seconds to return to the surface and the max height of the ball is 110.25 ft.
