Always use significant figure rules. remember that these rules apply to all numbers that are measurements. an object moves in uniform circular motion at 25 m/s and takes 1.0 second to go a quarter circle. what is the radius of the circle? r = m 0.063 m 0.99 m 16 m 50. m

16 m

Step-by-step explanation:

We have the following data:

is the velocity of the object moving in uniform circular motion

is the time it takes to the object to go of a complete circle

We need to find the radius of the circle, and this can be found by the following equation:

(1)

Where is the circumference of the circle and is the period for a complete circle.

Hence, isolating we have:

(2)

(3)

Finally:

(4)
