A ball rolls around a circular track with an angular velocity of 4π rad/s. what is the period of the motion

1 answer:

4 0

The period, T, is the time required for one revolution.

The angular velocity is 4π rad/s.
Because one revolution = 2π radians, the period is
T = (2π rad)/(4π rad/s) = 0.05 s.

Answer: 0.5 s

Korolek [52]

Answer:

rotating movement on itself, it creates the phenomenon of day and night.

Explanation:

When a body that rotates around a star (translational movement), rotates on itself (rotational movement), the light from the star cannot reach the opposite part of the object, so at these points it is NIGHT and when in the rotation movement the point is in front of the star it is DAY.

Therefore, in rotating movement on itself, it creates the phenomenon of day and night.

Calculate the average times it took the car to travel 0. 25 and 0. 50 meters. Record the averages, to two decimal places, in Tab

Illusion [34]

The average speed of the given car is 2.22 s and 3.13 s for 0.25 m and 0.50 m distance respectively.

<h3>How to calculate the Average speed?</h3>

The average speed can be calculated by adding the speed of each trial divided by the number of trials,

For 0.25 m the average speed will be:

$S_{avg} = \dfrac{2.24 + 2.21 + 2.23}{ 3}\\\\S_{avg} = 2.22$

For the 0.50 m, the average speed will:

$S_{avg} = \dfrac {3.16 + 3.08 + 3.15} {3 }\\\\S_{avg} = 3.13\rm \ s$

Therefore, the average speed of the given car is 2.22 s and 3.13 s for 0.25 m and 0.50 m distance respectively.
