With what velocity does it hit the ground?​
Serggg [28]

That depends on a number of things that we don't know because you haven't told us.

If any of the things on this list changes, then the answer to the question changes:

-- What is "it" ?

-- Was it dropped, thrown, fired, or launched ?

-- From what height above the ground ?

-- With what speed ?

-- In what direction ?

-- What is the acceleration of gravity where this took place ?

-- Did any drag act on it, due to liquid or gas, before it hit the ground ?

If the ball leaves the projectile launcher at a speed of 2.2 m/s at an angle of 30ᴼ, and the projectile launcher is on a table a
IgorC [24]

Answer: 1.12 m

Explanation:

This situation is related to parabolic motion, hence we can use the following equations:

y=y_{o}+V_{o}sin \theta t-\frac{g}{2}t^{2} (1)

x=V_{o} cos \theta t (2)

Where:

y=0 m is the ball final height (when it hits the ground)

y_{o}=1.1 m is the ball initial height

V_{o}=2.2 m/s is the initial velocity

\theta=30\° is the angle at which the ball was launched

t is the time

g=9.8 m/s^{2} is the acceleration due gravity

x is the horizontal distance the ball travels

Rewriting (1) with the given values:

0 m=1.1 m+(2.2 m/s)(cos 30\°)t-\frac{9.8 m/s^{2}}{2}t^{2} (3)

Multiplying all the eqquation by -1 and rearranging:

4.9 m/s^{2} t^{2}-1.1 m/s t-1.1 m=0 (4)

So, since we have a quadratic equation here (in the form of0=at^{2}+bt+c,  we will use the quadratic formula to find  t:  

t=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}   (5)

Where a=4.9, b=-1.1, c=-1.1  

Substituting the known values and choosing the positive result of the equation, we have:  

t=\frac{-(-1.1)\pm\sqrt{(-1.1)^{2}-4(4.9)(-1.1)}}{2(4.9)}  

t=0.59 s (6)

Now, substituting (6) in (2):

x=(2.2 m/s)(cos 30\°)(0.59 s) (7)

x=1.12 m (8) This is the horizontal distance at which the ball hits the ground.

two coins lie 1.5 meters apart on a table. they carry identical electric charges. approximately how largeis the charge on each c
BARSIC [14]

The charge on each coin is equal to

Given the following data:

Force = 2.0 Newton

Radius = 1.5 meters

To determine the charge on each coin, we would apply the law of electrostatic forces:

Mathematically, the law of electrostatic forces is given by the formula:

Note:  (since the coin carry identical electric charges).

Therefore, the formula becomes:

Making q the subject of formula, we have:

Substituting the given parameters into the formula, we have;
