Q:

A tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an initial speed of 110 feet per second. After how many seconds does the ball attain its maximum height?

A) 2.87 sec	B) 3.44 sec
C) 4.65 sec	D) 5.41 sec

Answer & Explanation Answer: B) 3.44 sec

Explanation:

It is launched vertically with an initial speed of 110 ft/sec.

It will reach maximum height when the speed drops to 0.

Vo=110 feet per second

ho=2 feet

So, h(t) = -16t^2 +110t +2

Take the derivative: h'(t) = 110 -32t

The maximum height will be at the inflection when the derivative crosses the x-axis, then h'(t)=0.

So, set h'(t)=0 and solve for t:

0 = 110 -32t

-110 = -32t

t=3.4375

t=3.44 seconds.
