John stands on the topmost tier of seats in a baseball stadium, and throws a ball out onto the field with a vertical upward velocity of 60 ft/sec. The ball is 50 feet above the ground at the moment he releases the ball. When does the ball land?

Question

lifeisadangerousgame · Answer

The height function h(t) is given by h(t) = $$h(t) =1/2\gt^2 + v _{0}t + k$$
Where g is 32 ft/sec^2, $$v _{0}$$ = 60 ft/sec and k = 50 ft
