A ball is thrown straight down from the top of a 497-foot building with an initial velocity of -15 feet per second. Use the position function below for free-falling objects.

s(t) = -16t2 + v0t + s0

What is its velocity after 2 seconds?
v(2) =  ft/s

What is its velocity after falling 316 feet?
v =  ft/s

Using calculus, it can be shown that if a ball is thrown upward with an initial velocity of 32 ft/s from the top of a building 594 ft high, then its height h above the ground t seconds later will be h = 594 + 32t − 16t2. During what time interval (in seconds) will the ball be at least 34 ft above the ground? (Enter your answer using interval notation.)
