If you get a ticket for speeding, it is based on your average speed or instantaneous speed? Explain
1 answer:
Answer:
Instantaneous speed
Explanation:
Usually the speed measuring guns are used to measure the speed at a certain instant, so the measured speed is instantaneous.
The average speed is determined by the expression final distance minus initial distance divided by time
The instantaneous speed is determined in the same way as the average, but with the exception that the travel displacements are shorter (very close one each other).

Explanation:
The given data is as follows.
Angular velocity () = 2.23 rps
Distance from the center (R) = 0.379 m
First, we will convert revolutions per second into radian per second as follows.
= 2.23 revolutions per second
=
= 14.01 rad/s
Now, tangential speed will be calculated as follows.
Tangential speed, v =
= 0.379 x 14.01
= 5.31 m/s
Thus, we can conclude that the tack's tangential speed is 5.31 m/s.
