A ball is launched straight up in the air from a height of 6 feet. Its velocity (feet/second) t seconds after launch is given by f(t) = - 30t + 280. What is the ball's average velocity from 1 seconds to 6 seconds? Between 1 seconds and 6 seconds the ball's average velocity is If necessary, round the answer to two decimal places. feet/second. f(t) = - 16t + 359t + 8 is the height (in feet) of a ball launched straight up t seconds after it is launched. What is the average velocity of the ball from 3.7 to 8.4 seconds? ft/sec. If necessary, round to two decimal places. If there is more than one correct answer, separate them with commas.
