1. Potential Energy = mgh
h = U_g / (mg) = 14 / (17 * 9.81) = <u>0.084 m above the ground.</u>
2. Kinetic Energy = 1/2 mv^2
m = 2K_e / (v^2) = <u>2.45 kg</u>
3. U_g = mgh = (1200)(9.81)(24) = <u>282528 J</u>
4. U_g = mgh = (478)(9.81)(150) = <u>703377 J</u>
5. U_g = mgh = (100)(9.81)(12.5) = <u>12262.5 J</u>
6. h = U_g / (mg) = 14 / (17 * 9.81) = <u>0.084 m above the ground.</u>
<u />
7. m = U_g / (gh) = 1500 / (9.81 * 35) = <u>4.37 kg</u>
4+6+6+2=18(balls)
Another way 1)4+6=10(balls)-green and blue
2)6+2=8(balls)-green and blue
3)10+8=18(balls)-total probability
Answer:
5 ft
Step-by-step explanation:
Since we have a rectangle, we know for sure that perimeter = double the width and double the height. Algebraically, that looks like:
P = 2W + 2H
Let's sub in the given values, P and W:
18 = 2(4) + 2H
Now, let's solve for the height, H:
18 = 8 + 2H
10 = 2H
10/2 = H
<u>5 = H</u>

The length of one segment is 15 cm and other segment is 60 cm
Step-by-step explanation:
Let x be the length of one segment and y be the length of other segment
Then according to given statement
x+y=75 Eqn 1
And
one the segments are four times the other
x=4y Eqn 2
Hence,
The length of one segment is 15 cm and other segment is 60 cm

Here we have to know the conversion between feet and inches.
1 Feet = 12 inches (This is given and is to be known)
So the 5 feet wide footbridge when converted to inches would be about 5*12 = 60 inches
The width of the footbridge in inches = 60 inches
Each wooden plank is 6 inches,
So the number of wooden planks that are required to build the foot bridge of 60 inches = 60/6 = 10 planks
Hence, the path path is 10 planks wide
