Acar of mass 1000kg goes on a circular track with a diameter of 100m. the car moves at constant speed and makes 6 revolutions in 2 min.

the frequency is hz

the period of the car is s

the speed of the car is m/s

,20,15.7

Explanation:

Frequency is defined as the number of revolutions made the object in unit time.

Given that it takes minutes revolutions.

So, revolutions can be completed in minute.

So, revolutions can be completed in a second.

So,frequency is

Period of a object is the inverse of frequency.

Inverse of frequency

So,period is .

Speed of car is the given by the ratio of distance covered in one revolution to the time period.

Distance travelled in one period is where is the diameter.

Given that

So,distance travelled in one revolution

Time period is .

Speed is
