Answer
(a) $240\ ft$
(b) $1$ and $5\ sec$
(c) Going up from 0 to 3 seconds, going down from 3 to 7 seconds.
(d) $256\ ft$, $3\ sec$
(e) $7\ sec$
Work Step by Step
(a) Locate $t=2\ sec$, go upwards to meet the curve, read its vertical value as $h(2)=240\ ft$
(b) Locate $h=192\ ft$, go horizontally to meet the curve, read its t-values as $t=1, 5\ sec$
(c) Going up from 0 to 3 seconds, going down from 3 to 7 seconds.
(d) Locate the maximum at $h=256\ ft$ read the time as $t=3\ sec$
(e) The ball hits the ground when $h=0$, the total time is $t=7\ sec$
