Greeley [361]
We separate equation by looking at x and y projection separately. 
Let us look at the x projection first.
Motion starts with initial velocity v_0cos(45) because there is no force acting along the x-axis we don't have any acceleration along the x-axis.  Our equation would be:
x=v_0cos(45)\cdot t
Now our y equation will be a little bit more complicated. There is gravity working against our projectile and we also have to take into effect the hight from which the projectile is launched.
With all that in mind let us write the equation for y projection:
y=h+v_0sin(45)\cdot t-g \frac{t^2}{2}
The term -g \frac{t^2}{2} represents gravity and as you can see it is negative, which means gravity is pulling our projectile down. 
There is one more thing we can do. We can express initial velocity v_0 in relation to circular motion used to launch the projectile.
v_0=w\cdot r
Where r is the length of the letter used to launch the projectile, and w is angular velocity.  
If we combine our x and y equations we can get the trajectory of our projectile.
y=h+x- \frac{gx^2}{2\cdot (wr)^2cos^2(45)}
This is the equation of a parabola. If you follow this link(https://www.desmos.com/calculator/vogcuygjhs) it will take to an interactive graph where you can see how trajectory looks like depending on some of the paramaters.

The foot of a ladder is placed 7 meters from a wall. If the top of the ladder rests 9 meters up on the wall, how long is the lad
nekit [7.7K]

We can find the length of the ladder by squaring the known digits, adding them, and finding the square root of the sum. This would mean our first equation, after squaring, will look like this:

49+81=130

Now that we have <em>c</em> squared, we can go through and find the approximate square root, which is 11.4. That would mean the ladder is 11.4 meters long.

Use the Distributive Property to rewrite the algebraic expression. 7(6m + 7)
jeka57 [31]

Step-by-step explanation:

first, distribute 7 to 6m (this means 7 • 6m)

7 • 6m = 42m

then distribute 7 to 7 (which is 7 • 7)

7 • 7 = 49

your simplified expression is <u>42m + 49</u>. i hope this helps! have a great day <3
