Part of a cheerleading routine is throwing a flyer straight up and catching her on the way down. The flyer begins this move with

umka2103 [35]

Answer:

Step-by-step explanation:

Given that a flyer begins from earth and thrown up with a velocity of 30 ft/sec vertically.

u = initial velocity = 30 : a = -g = 32 ft/sec^2

s(0) =initial height =4 ft.

We have the equation

where u = initial velocity : v= final velocity : s = distance travelled and a = acceleration. Here final velocity is found out as follows

Substitute to get

Since v cannot be negative, the flyer’s center of gravity cannot ever reach 20 feet.

----------------------------------

To reach 25 ft, put s = 25

and v must be atleast 0

Then we have

Hence if thrown with initial velocity of 40 ft /sec, it will reach a height of 25 ft.

A blueberry shortcake 49 feet, 4 inches long and 9 feet wide was made in Canada on September 19, 1995. The height of the shortca

Answer:

296 cubic feet

Step-by-step explanation:

First and foremost, you have to have everything in either feet or inches. Right now they are in both. Since the answer is asked for in feet, let's convert everything to feet. The width is already in feet, so that's good.

However, even though the length is 49 feet, we still have to convert the 4 inches part of that to feet. Using the fact that there are 12 inches in a foot:

$4in.*\frac{1ft}{12in.}=\frac{1}{3}ft$ so we have
