A ping pong ball rolls off a 5.Om high table and lands on the floor, 3.0maway from the table. How long is the ball in the air?

Answers

Answer:

The ball was 1.01 seconds in the air

Explanation:

Horizontal Motion

When an object is thrown horizontally with a speed v from a height h, the range or maximum horizontal distance traveled by the object can be calculated as follows:

$\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}$

If we know the value of d and h, we can solve the equation for v:

$\displaystyle v=d\cdot\sqrt{\frac {g}{2h}}$

Since the horizontal speed is constant, we can calculate the time the ball was in the air by using the equation:

$\displaystyle t=(d)/(v)$

The ping pong ball rolls from a height of h=5 m and lands on the floor a distance of d= 3 m away from the table. Calculate the speed:

$\displaystyle v=3\cdot\sqrt{\frac {9.8}{2\cdot 5}}$

$\displaystyle v=3\cdot\sqrt{\frac {9.8}{10}}$

Calculating:

$v=2.97\ m/s$

Now calculate the time:

$\displaystyle t=(3)/(2.97)$

$t=1.01\ sec$

The ball was 1.01 seconds in the air

Note: The time does not depend on the distance d at all. If we borrow the equation from free-fall motion, the time can be calculated with:

$\displaystyle t=\sqrt{\frac {2h}{g}}=\sqrt{\frac {10}{9.8}}=1.01\ sec$

Suppose for your cookout you need to make 100 hamburgers. You knoe that 2.00 pounds will make 9 hamburgers. How many pounds will u need?

Answers

The cook needs to make 100 hamburgers. The price of 9 hamburgers is 2 pounds. Then 22.2 pounds are needed to bring 100 hamburgers.

What are methods of finding price values ?

There are simple mathematics to find the price of a material based on the data we have on it. For example if we know the price of one unit of that material then multiply the price by the number of units we want to buy.

If know the price of a bulk or certain number of materials, then find the price of one material from it.

Here, the price of 9 hamburgers is given 2 pound. Then, the price of one hamburger is :

2/9 = 0.22.

Now, multiply the value of one hamburger with the number that we want. We want 100 hamburgers. Then,

100× 0.22 = 22.2 pounds.

Therefore, 22.2 pounds are needed for 100 hamburgers.

if
2.0 pound will make 9 hamburgers
so 100 hamburgers will make by pounds = 100/9 × 2.0 = 22.2 pounds

the ans is (22.22 pounds will make 100 hamburgers)
