Answer:
i think the answer is constant
Answer:

Explanation:
Velocity can be found using the following formula:

where p is the momentum and m is the mass.
The woman has a mass of 55 kilograms and a momentum of 200 kilogram meters per second.

Substitute the values into the formula.

Divide. Note that the kilograms, or kg, will cancel each other out.


The woman's velocity is 3.63636364 meters per second.
Answer:
-6112.26 J
Explanation:
The initial kinetic energy,
is given by
} where m is the mass of a body and
is the initial velocity
The final kinetic energy,
is given by
where
is the final velocity
Change in kinetic energy,
is given by

Since the skater finally comes to rest, the final velocity is zero. Substituting 0 for
and 12.6 m/s for
and 77 Kg for m we obtain

From work energy theorem, work done by a force is equal to the change in kinetic energy hence for this case work done equals <u>-6112.26 J</u>
Answer:
are known as hydrocarbons. the saturated hydrocarbons are known as alkanes.
Answer:
Air moves from regions of high pressure to regions of low pressure.
Explanation:
When airs moves horizontally from regions of high pressure to low pressure, it creates wind. If the difference between high and low pressure is greater, then it makes the wind faster.
Best of Luck!
