instantaneous Velocity of a Ball In physics it is shown that the height s of a ball thrown straight up with an initial velocity of from ground level is
where is the elapsed time that the ball is in the air.
(a) When does the ball strike the ground? That is, how long is the ball in the air?
(b) What is the average velocity of the ball from to ?
(c) What is the instantaneous velocity of the ball at time ?
(d) What is the instantaneous velocity of the ball at ?
(e) When is the instantaneous velocity of the ball equal to zero?
(f) How high is the ball when its instantaneous velocity equals zero?
(g) What is the instantaneous velocity of the ball when it strikes the ground?
