Answer:

x = -95, y = 22.75, z = -6.625

Step-by-step explanation:

We start with the line that only has 1 variable, since that's easiest to solve.

2y + 162 = -28

2y = -190

y = -95

Then we go to the line that has 2 variables and substitute y with -95, since that's what y is equal to.

4x -95 = -4

4x = 91

x = 22.75

Then we do the last line with the answers we've gotten so far.

-14(22.75) - 3(-95) + 4z = 7

-318.5 + 285 +4z = 7

4z = -26.5

z = -6.625

A ball is rolled at a velocity of 12m/sec.after 36 seconds,it comes to a stop what is the acceleration of the ball?
miv72 [106K]

acceleration of ball is \frac{-1}{3}\,\,m/sec^2

Step-by-step explanation:

Initial Velocity = 12m/sec

time = 36 s

Final Velocity 0 m/sec (ball comes to stop)

Acceleration= ?

The formula used to find acceleration is:

Acceleration=\frac{Final\,\,Velocity-Initial\,\,Velocity}{Time}

Putting values and finding acceleration:

Acceleration=\frac{Final\,\,Velocity-Initial\,\,Velocity}{Time}

Acceleration=\frac{0-12}{36}

Acceleration=\frac{-12}{36}

Acceleration=\frac{-1}{3}\,\,m/sec^2

So, acceleration of ball is \frac{-1}{3}\,\,m/sec^2
