1) The average velocity is 56 m/min
2) The average velocity is -83 m/min
Explanation:
1)
The average velocity of an object is given by
where
d is the displacement (change in position)
t is the time elapsed
In the graph in the problem, the displacement corresponds to the distance, therefore to the change in the y-variable (), while the time elapsed is the change in the x-variable (
), so the average velocity can be written as
At point A, we have:
At point B, we have:
So, we have
So the average velocity is
2)
In this part instead, we have the following:
At point F, we have:
At point H, we have:
So, we have
So the average velocity is

Answer:
Explanation:
The angular momentum of that same disk-sphere remains unchanged the very same way before and after the impact of the collision when the clay sphere adheres to the disk.
= constant.
The overall value of such moment of inertia is now altered when the clay spherical sticks. Due to the inclusion of the clay sphere, the moment of inertia will essentially rise. As a result of this increase, the angular speed w decreases in value.
Recall that:
The Kinetic energy is given by:
where;
is constant and w reduces;
As a result, just after the collision, the system's total kinetic energy decreases.
