The pair of points lies on the same line with the given slope. Find x.

Darya [45]

Answer:

x = 6

Step-by-step explanation:

Find the equation of the line

y = mx + b

Use the slope given 3 and the x of 4 and the y of 11 from the point given (4,11)

11 = 3(4) +b Solve for y

11 = 12 + b Subtract 12 from both sides

-1 = b

y = 3x -1 This is the equation of the line. Substitute in 17 for y and solve for x

17 = 3x -1 Add 1 to both sides

18 = 3x Divide both sides by 3

6 = x

A 6.50 kg crate is suspended from the end of a short vertical rope of negligible mass. An upward force F(t) is applied to the en

borishaifa [10]

Answer:

$F=158.86 N$

Step-by-step explanation:

We are given that

Mass of crate=m=6.5 Kg

Height, $y(t)=(2.80m/s)t+(0.610m/s^3)t^3$

We have to find the magnitude of F when t=4 s

Differentiate w.r.t t

$v=\frac{dy}{dt}=2.8+3(0.61)t^2$

Again differentiate w.r.t t

$a=\frac{dv}{dt}=3\times 2(0.61)t$

$a=3.66tm/s^3$

Substitue t=4

$a=3.66\times 4=14.64m/s^2$

$F-mg=ma$

Where $g=9.8m/s^2$

Substitute the values

$F-6.5\times 9.8=6.5\times 14.64$

$F=6.5\times 14.64+6.5\times 9.8$

$F=158.86 N$
