Tom drops a coin from the top of a building. Tom is 90 meters from the ground when he drops the coin. A) What is the height of t

Delvig [45]

Disregarding air friction, the distance traveled by an object due to gravity is : H = 0.5*g*t^2.   g is the gravitational constant at the surface of earth.

g= 9.81 m/s^2

After 3 seconds, Distance = .5*9.81*9 = 44.15 meters traveled.

Since it was dropped from a height of 90 meters, the current height is 90 - 44.15 = (a) 45.85 meters

(b) It has to travel 90 meters to hit the ground . So we must find t

Using the same equation

t = (2*H/g)^.5

t = (2*90/g)^.5 = 4.28 seconds until it hits the ground

1.4 divided by 72.8 work form please

Fittoniya [83]

$\frac{1.4}{72.8}$$

Multiply the numerator and denominator by: 10

$\frac{14}{728}$$$

Divide 14 by 728 to get 0

$\begin{gathered}728 \frac{0 .}{14.0} \\\underline{0} \\1 \overline{4} 0\end{gathered}$

Divide 140 by 728 to get 0

$\begin{gathered}7 2 8 \longdiv { 1 4 . 0 0 } \\\underline{0} \\140 \\\underline{0} \\1400\end{gathered}$

Divide 1400 by 728 to get 1

$\begin{gathered}728 \frac{0.01}{14.000} \\\underline{0} \\1 \overline{4} 0 \\\underline{0} \\1400 \\\frac{728}{6720}\end{gathered}$

Divide 6720 by 728 to get 9

$\begin{gathered}728 \frac{0.019}{14.0000} \\\frac{0}{140} \\\frac{0}{1400} \\\frac{728}{6720} \\\frac{6552}{1680}\end{gathered}$

Divide 1680 by 728 to get 2

$\begin{aligned}&728 \frac{0.0192}{14.00000}\\&\frac{\underline{0}}{140}\\&{ }_{140} \frac{0}{0}\\&\frac{728}{6720}\\&\frac{6552}{1680}\\&\frac{1456}{2240}\end{aligned}$

Divide 2240 by 728 to get 3

Addition, subtraction, multiplication, and division are the four fundamental arithmetic operations in mathematics. The type of arithmetic operation has been selected based on the requirements of the task.

For instance, we must divide 100 by 25 to distribute 100 chocolates evenly among 25 youngsters.

Each youngster will thus get 4 chocolates. In this article, we'll go through one of the arithmetic operations called "Division or Divide," along with its symbol, division math formula, and several instances that have been solved.

Split, in its simplest form, is to divide into two or more equivalent portions, spaces, groups, or divisions. Split, in plain English, is to provide the entire item to a group in equal portions or to divide it into equal pieces. Let's say a square is divided into two triangles with equal areas by a diagonal. A division operation may or may not provide an integer as the outcome. The outcome may occasionally take the form of decimal numbers.
