The complete question in english is written below:
A toy car spins on a circular track 45 cm in diameter. If it uses 0.5 seconds to make a complete circle, determine:
a- period and frequency in one circle
b-the distance it travels around the circular path
c-linear velocity
d-angular velocity
e-centripetal acceleration
a- period and frequency in one circle
According to the given information the period is
and since the frequency
is the inverse of the period, we have:


b-the distance it travels around the circular path
Here we have to calculate the perimeter
of the circular path:

Where
is the diameter

c-linear velocity
We can calculate the linear velocity
by:


d-angular velocity
Angular velocity
is given by:
e-centripetal acceleration
Centripetal acceleration
is given by:



Answer:
siege
Explanation:
siege - a military operation in which enemy forces surround a town or building, cutting off supplies, with the aim of compelling the surrender of those inside
