How long will it take for an object to fall from 15m?

1 answer:

5 0

The time taken by the object to fall from 15 m on the Mercury which has a gravity of 3.7 m/s² is 10.54 seconds.

<h3>What is kinematics?</h3>

It is the study of the motion of a body without considering mass. And the reason behind them is neglected.

The object is on Mercury and starts falling from rest.

As it is on Mercury there is no air resistance to account for.

Gravity on Mercury is 3.7 m/s².

Then the time taken by the object to fall from 15 m will be given as

$\rm t = \sqrt{2gh}\\\\t = \sqrt{2\times 3.7\times 15}\\\\t = 10.5356 \approx 10.54 \ seconds$

More about the kinematics link is given below.

Help me solve this equation. Find f(x)-g(x)

mojhsa [17]

Answer:

- 2x³

Step-by-step explanation:

f(x) - g(x)

= $x^{\frac{1}{2} }$ - x - (2x³ - $x^{\frac{1}{2} }$ - x) ← distribute parenthesis by - 1

= $x^{\frac{1}{2} }$ - x - 2x³ + $x^{\frac{1}{2} }$ + x ← collect like terms )

= - 2x³

Which of the following is an example of quantitative data? A the player’s number on a baseball uniform B the serial number on a

Taya2010 [7]

Answer:

The number of people in a waiting line is a quantitative data as we can count them.

Step-by-step explanation:

Consider the provided information.

The value of quantitative data can be determined by counting or measuring something.

Now consider the provided options.

The player’s number on a baseball uniform, the serial number on a one-dollar bill and the part number of an inventory item is not a quantitative data because we can't measure them.

The number of people in a waiting line is a quantitative data as we can count them.

I barely ask questions but I really need help with #3 and a little with 4. On number four I got 1 1/20 which doesn’t seem right.

Let r, g and b represent red, green and blue.

r+g+b = 74

r=g-1

b=r+g

Again, r+g+b = 74. Let's substitutte r+g for b: r+g+(r+g) = 74.

Next, let's eliminate r. Use r=g-1. Then g-1 + g + g-1 + g = 74

Combining the g terms, 4g - 2 = 74 => 4g = 76 => g = 19

Recall that r=g-1
and
b=r+g

Find r. If r=g-1, and g=19, then r = 19-1=18

Find b: b = r+g = 18+19=37

So there are 37 blue candies, 18 red candies and 19 green candies.

Check: 37+18+19=74 ??? Yes.

What is the slope of (8,10), (-7,14)

Murrr4er [49]

Reduce the expression, if possible, by cancelling the common factors.

Exact Form:
−4/15

Decimal Form:
−0.26

Basically do
y2-y1 divided by x2-x1
14-10 divided by -7-8
which equals -4/15
