Two boys are throwing a baseball back and forth. The ball is 4 ft above the ground when it leaves one child’s hand with an upwar

d velocity of 36 ft/s. If acceleration due to gravity is –16 ft/s2, how high above the ground is the ball 2 s after it is thrown?

Answer:

The ball is about 44 ft\\ above the ground

Step-by-step explanation:

As per newton's second law of motion

S = ut + \frac{1}{2} at^2\\

Substituting the given values in above equation, we get -

S = (36)(2) + \frac{1}{2} (-16)(2^2)\\= 40 ft\\

The total height including the height of ball from where it is throws

40 ft  + 4 ft\\= 44 ft\\

Answer:

<h2><em><u>m = 20</u></em></h2><h2><em><u>a = 48</u></em></h2><h2><em><u>These are the answers.</u></em></h2>

Step-by-step explanation:

1. m/-8 = -2.5

*-8 = *-8

m = -2.5*-8

m = 2.5*8

<em><u>m = 20</u></em>

2. 7/8a = 42

*8            *8

7a = 336

/7       /7

a = 336/7

<em><u>a = 48</u></em>

<em><u></u></em>

Hope this helped,

Answer:

0.5 m/s

Falling at 32 feet/s

Step-by-step explanation:

For the first question, since it only asks for the average time between 2 and 8 seconds, those are the only two important values. When taking the inputs and outputs for 2 and 8 seconds after the throw ((2,3) and (8,6) respectively), we can take the average change by finding the change in y/change in x, so we have (6-3)/(8-2)=0.5 meters/second.

For the second question, we can similarly just take the values from the initial drop (144) and after two seconds (80) to get that the rate of change is (144-80)/(-2)=-32, so it's falling at 32 feet/second.

Let me know if you have any questions!

Which inequality is true?

Answer:

C. | -100 | > 50

Step-by-step explanation:

The left side 100 is greater than 50. Using || pretty much makes the number the inverse/opposite in any equation.

Hopefully this helps :)
