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: The density is greater at point C
Explanation: At that point
The convention current slowly cools off
The atomic procedure clarifies why this is the situation is beginning from carbon ( the nuclear number is 6), the most widely recognized atomic responses include the combination of an extra helium core. I hope the answer will help you.
unless...the wall simulaneiously exerts the same amount of force on you.
Inertia is that quantity which depends solely upon mass. The more mass, the more inertia. Momentum is another quantity in Physics which depends on both mass and speed.
