Answer to Question #238595 in Calculus for steve

Question

A ball tossed h feet in the air will stay in the air for T= 0: 5p (square root then) h

seconds. Note that when a question uses units the final answer should include appropriate units.

(a) Suppose a ball is tossed 4 feet in the air. When will the ball come down?

(b) If a ball remains in the air for 2.5 seconds, how high was it tossed

Answer 1

$T=\sqrt{h}, h$ in $ft$ , $t$ in $sec$

(a) Given $h=4 \ ft$

Then

$$T=\sqrt{4} \ sec=2\ sec$$

(b) Given $T=2.5\ sec$

Then

$$h=(2.5)^2\ ft=6.25\ ft$$
