# Calculate Speed on a Circular Track with Radius 135m

• Brittykitty
In summary, to find the speed of a student running on a circular track with a radius of 135 m and accelerating at 0.60 m/s2, the formula is v2=aR and the result should be multiplied, not divided. To get the final speed, take the square root of the result.

A student runs on a circular track that has a radius of 135 m. If she accelerates at 0.60 m/s2, what is her speed?

a=V2/R?
0.62m/s2 /135m??

I think I def have the wrong formula, is anyone able to help me out to find speed?

you have the correct formula, v2=aR, so just get v

How do I get the v? :) thank you

take the square root.

v2=aR
0.62m/s2 /135m
0.004
sqare root = 0.26?
Im def doing something wrong, maybe I am putting it in my calculator wrong

You should be multiplying, not dividing as you are doing.

thank you! :)

## 1. How do you calculate speed on a circular track with a radius of 135m?

The formula for calculating speed on a circular track is: v = (2 * π * r) / t, where v is the speed, r is the radius, and t is the time it takes to complete one full revolution on the track.

## 2. What is the unit of measurement for speed on a circular track?

Speed on a circular track is typically measured in meters per second (m/s).

## 3. How does the radius of the track affect the speed?

The radius of the track directly affects the speed, as seen in the formula. The larger the radius, the higher the speed will be, assuming the time taken to complete one revolution remains constant.

## 4. Can the speed on a circular track be negative?

No, the speed on a circular track cannot be negative. Since speed is a measure of distance traveled over time, it cannot be negative as it indicates a backwards movement.

## 5. How can I convert the speed on a circular track from m/s to km/h?

To convert from meters per second (m/s) to kilometers per hour (km/h), simply multiply the speed in m/s by 3.6. For example, if the speed on a circular track is 10 m/s, the equivalent speed in km/h would be 10 * 3.6 = 36 km/h.
