Hello AljakeVillena!
You pull horizontally on a 50-kg crate with a force of 450 n and the friction force on the crate is 250 n. the acceleration of the crate is ?
Given,
- mass of crate = 50 kg
- Force you pull it with = 450 N
- Frictional force = 250 N
- Acceleration = ?
__________________
Let's first find the total force/net force acting on the crate. The total force will be :-
- 450 N - 250 N = <u>2</u><u>0</u><u>0</u><u> </u><u>N.</u>
We subtracted the forces because both the forces act on opposite directions.
__________________
Now, let's find the acceleration of the crate. To find the acceleration we must divide the net force by the mass. So,..
- Acceleration = Force/mass
- a = F/m
- a = 200/50
- <u>a = 4 m/s²</u>
__________________
So, the acceleration of the crate is <u>4</u><u> </u><u>m/</u><u>s²</u><u>.</u>

Answer: -8 degrees C.
Step-by-step explanation:
if you hear the what is the difference then you know you'll subtract:)
-20 - -12 = -8 degrees C.
First divide by 2, then you have
1/2x-7=-3
Then add 7 to both sides
1/2x=4
Then then divide by 1/2(which is the same as multiplying by 2)
And
x=8
•y-intercept is 20
•y-intercept represents how many glass bottles you need to earn $1.00 if you have 0 aluminum cans
•x-intercept is 50
•x-intercept represents how many aluminum cans you need to earn $1.00 if you have 0 glass bottles
Answer:
Step-by-step explanation:
If you want the surface area of a rectangular prism, then you'll use a formula resembling this:
A = 2(area of end) + 2(area of top) + 2 (area of side).
Example: suppose the dimensions of the prism are 3 in by 5 in by 8 in.
Then the total surface area is:
A = 2(3*5) + 2(3*8) + 2(5*8) square inches, or 2(15) + 2(48) + 2(40) sq in, or
A = 30 + 96 + 80 sq in, or A = 206 sq in
