You want to calculate the displacement of an object thrown over a bridge. Using -10 m/s^2 for acceleration due to gravity, what

MrRissso [65]

Answer

The total displacement of the object is 320 m

Solution-

From the formulas of mechanics,

$s=ut+\frac{1}{2}at^{2}$

Where,

s = displacement

u = initial velocity = 0 ( ∵ As the body was in rest in the beginning )

t = time taken = 8 s

a = acceleration = -10 m/s² ( ∵ -ve is because of the downward motion)

Putting all the values,

$s= 0 \times 8 + \frac{1}{2}(-10)8^{2} = -320 \ m$ ( ∵ -ve displacement means it is in downwards)

Find the slope-intercept form of the equation of the line passing through the given points.

Ugo [173]

$The\ slope-intercept\ form:y=mx+b\\\\The\ slope-point\ form:y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

$(1;\ 1)\to x_1=1;\ y_1=1\\\left(3;-\dfrac{1}{5}\right)\to x_2=3;\ y_2=-\dfrac{1}{5}.\\\\Subtitute:\\\\m=\dfrac{-\frac{1}{5}-1}{3-1}=\dfrac{-1\frac{1}{5}}{2}=-\dfrac{\frac{6}{5}}{2}=-\dfrac{\not6^3}{5}\cdot\dfrac{1}{\not2_1}=-\dfrac{3}{5}$

$y-1=-\dfrac{3}{5}\left(x-1\right)\\\\y-1=-\dfrac{3}{5}x+\dfrac{3}{5}\ \ \ \ |add\ 1\ to\ both\ sides\\\\\boxed{y=-\frac{3}{5}x+1\frac{3}{5}}$

sergiy2304 [10]

Answer:

Third graph C.

Step-by-step explanation:

3a + 11 > 5

Subtract 11 from both sides

3a > -6

Solve for a

a = -6/3

a > -2

so a would be all numbers greater than -2
