A ball is thrown upward. Its height hin feet is given by h(t) = 104t - 16t², where t is the time elapsed in seconds. (a) What is the velocity v of the ball at t = 0 s, t = 1 s, and t = 4 s? h'(0) = 0 X h'(1) = 88 h'(4) = 160 ft/s X ft/s X ft/s (b) At what time t does the ball strike the ground? t = 6 X S (c) At what time t does the ball reach its highest point?
