Complete question:
<em>A skateboarder rolls horizontally off the top of a staircase and lands at the bottom. The staircase has a horizontal length of 12.0m with a vertical drop of 2.0m. Calculate the speed of the skateboard. We can ignore air resistance.</em>
Using the following equations of motion;
Horizontal displacement
x = vt............ 1
Vertical component;
y = 1/2gt² ....... 2
v is the speed
t is the time
g is the acceleration due to gravity
Frim 1;
t = x/v ..... 3
Substitute equation 3 into 2;
From 2; y = 1/2gt² .
y = 1/2 g(x/v)²
y = 1/2 gx²/v²
y = gx²/2v²
v² = gx²/2y
v = √gx²/2y
Given;
x = 12m
y = 2m
g = 9.8m/s²
Substitute the given parameters into the give equation;
v = √(9.8)(12)²/2(4)
v = √(9.8)(144)/8
v = √1411.2/8
v = √176.4
v = 13.28m/s
Hence the approximate speed of the skateboard is 13.28m/s
A eclipse starts when one object in space is blocking an observer. Most commonly known as the moon blocking the sun. For us having a visual on eclipses we normally have two eclipses. We have the solar eclipse and the lunar eclipse. These are both very important on the timing and the cycles of the moon. A solar eclipse happens when the moon moves in front of the sun. This will cause a shadow to fall on only a few certain places on earth. Then a lunar eclipse is when the Sun, moon, and earth are perfectly aligned. With the earth being the middle the Sun casts its rays and causes a huge shadow on the moon.
Hope this helped!
