How much force was applied to a 5 kg object if it accelerated by 15 m/s/s

REY [17]

Answer:

We use Newton's second law of motion, which states that,

where:

is the net force applied in newtons

is the mass of the object in kilograms

is the acceleration of the object in meters per second squared

So, we get:

⋅

m/s

(

∵

≡

kg m/s

)

A piece of wire 40 cm long is to be cut into two pieces. One piece will be bent to form a circle and; the other will be bent to

Brums [2.3K]

<h3>The perimeter of circle = 17.6 cm</h3><h3>Perimeter of square = 22.4 cm</h3>

Step-by-step explanation:

The total length of the wire = 40 cm

Let us assume the circumference of the circle = k cm

So, the circumference of the square = ( 40 - k) cm

Now,as circumference of circle = 2πR

⇒2πR = k cm or, R = $(\frac{k}{2\pi})$

Area of the circle = πR²

or, A = $\pi (\frac{k}{2\pi} )^2$

$= \pi \times (\frac{k^2}{(2\pi)^2} ) = \frac{k^2}{4 \pi} \\\implies A = \frac{k^2}{4 \pi}$ ....... (1)

Similarly , perimeter of square = 4 x Side

⇒ 4 x Side = ( 40 - k) cm ⇒ S = $(\frac{40 - k}{4} )$

Area of the square = (Side)² = $(\frac{40 - k}{4} ) ^2$

Solving, we get: $A = \frac{1600 + k^2 - 80 k}{16}$ ....... (1)

So, combining (1) and (2), total area A is

$A = (\frac{k^2}{4 \pi} ) + \frac{k^2 + 1600 - 80 k }{16}$

or, we get: A = 0.07962 k² + 0.0625 k² + 100 - 5 k

A = 0.1422 k² - 5 k + 100

For axis of symmetry : $k = (\frac{-b}{2a} ) = (-\frac{-5}{2(0.1420}) = 17.6$

⇒ k = 17.6 inches

So, the perimeter of circle = 17.6 cm

Perimeter of square = (40 - 17.6 ) = 22.4 cm

I need help with slope

Serggg [28]

Answer:

1. (AB) y = 2/3x + -4

Step-by-step explanation:

Formula - y = m(x) + (y-intercept)

m = rise / run

"run = horizontal (left and right)

rise = vertical (up and down)"

the y intercept is always going to be where y is 0 at. (x, y) you will use your x to determine the intercept

So lets use your first question as an example

1. (AB) y = m(x) + (y-int)

y = m(x) + (-4)

the point goes to the right 6 points and goes up 4 points (rise / run)

y = 4/6(x) + (-4)

You can round up the fraction to 2/3

y = 2/3(x) + -4
