The height (in feet) above the ground of a golf ball depends on the time, t, (in seconds) it has been in flight. A golfer has hit a shot off the tee that has a height given by h(t)= 78.6(t) -16(t)^2
a. Sketch a graph of h(t) over the domain 0 ≤ t ≤ 6.
b. Solve h(t)=10 for t and explain what your numerical solution(s) mean in this real-world context.
