The particle moves with constant speed in a circular path, so its acceleration vector always points toward the circle's center.
At time , the acceleration vector has direction such that
which indicates the particle is situated at a point on the lower left half of the circle, while at time the acceleration has direction such that
which indicates the particle lies on the upper left half of the circle.
Notice that . That is, the measure of the major arc between the particle's positions at and is 270 degrees, which means that is the time it takes for the particle to traverse 3/4 of the circular path, or 3/4 its period.
Recall that
where is the radius of the circle and is the period. We have
and the magnitude of the particle's acceleration toward the center of the circle is
So we find that the path has a radius of
Answer:
follows are the responses to the given question:
Explanation:
The kinetic energy of every object moving. any entity lifted against the strength of gravity stores elastic potential of gravity.
Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed . So, if KE improves, it is valid that PE declines.
If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.
