If a ball is thrown into the air with a velocity of 36 ft/s, its height (in feet) after t seconds is given by y = 36t − 16t2. find the velocity when t = 1.

height (y) = 36t - 16t^2, where t = time in seconds (s). Our height (y) after 1s = 36(1) - 16(1)^2 y = 36 - 16 = 20 ft So it reached a height of 20 ft during that 1 second, which means that at that 1 second it had a velocity of 20ft/s, since v = d(distance)/t = 20ft/1s
