Answer:
The answer is D
Explanation:
The object with the heavy mass will reach first because the cause it is heaver so it will go faster
As both the skater pushed each other with a force, skater 1 will acquire greater velocity than skater 2 with heavier mass.
Answer: Option C
<u>Explanation:</u>
Here we can understand the scenario with the example of a particle collision. When two particles of different masses, one being lighter and the other being heavier, there will be a movement and change in velocities.
Now, when these two particle collide with each other, there will be an equal and opposite thrust or reaction on both the particles. The particle with heavier mass will not be able to acquire more velocity because of its weight whereas the lighter particle will be pushed far away, being less in mass.
We can also say that the heavier particle will exert more force as compared to the lighter one and hence, can easily push it far away. this is all because the force is directly proportional to the mass of the object.
Hence, just like the particle, when two skater try to push each other with a significant amount of force, skater 2 will win to exert more force and therefore, skater 1 will acquire greater velocity as compared to skater 2.
Answer:
r = b/2a
Explanation:
We know that force can be derived from potential energy:
F(r) = -dU(r) / dr
=> F(r) = -d/dr (ar² - br + c)
F(r) = -2ar + b
When this force is equal to zero,
F(r) = 0 = -2ar + b
=> 2ar = b
r = b/2a
This is the point where the force goes to zero.
