A potato launcher uses a spring that can apply a force of 20N to potato’s. He launches a 100 gram potato, what is the accelerati
shepuryov [24]

Answer:

200 m s^-2.

133.33 ms^-2.

100 m s^-2.

Step-by-step explanation:

Use Newton's Second Law of motion:

Force = mass * acceleration

The force is in Newtons so the mass must be in kilograms#

100 g = 0.1 kg. So:

20 = 0.1 * a

a = 20/ 0.1 = 200 m s^-2.

We calculate the acceleration for  the 150g and 200g potato in the same way.

What is the solution of the system? use elimination . -12x-y=6 17x+y=4
anyanavicka [17]
To clarify the systems of equations:

-12x - y = 6
17x + y = 4

We already have opposite coefficients for y, so combine the two equations together:

5x = 10

Divide both sides by 5 to get x by itself:

x = 2

Because we now know x, we can plug it into one of the equations.

We will plug this value into the first equation:

-12(2) - y = 6

-24 - y = 6

Add 24 to both sides.

-y = 30

Divide both sides by -1 to get y by itself.

y = -30

Using elimination, x = 2 and y = -30.

The first five terms of an arithmetic sequence are 8, 13/2, 5, 7/2, and 2. Which function, f(x), could be used to describe the x
juin [17]

Answer:

f(x) = 8 - 1.5x

Step-by-step explanation:

Here, we want to write a function that can be used to describe the x th term of the sequence

Mathematically, this can be calculated by looking at the numbers in the sequence

The difference between each successive term

is -1.5 ( 6.5-8, 3.5 -5)

So the formula for then x th term will be;

f(x) = 8 - 1.5x

where x refers to the number of the term , for example the 4th term
