An object makes a loop around a circular track (diameter = 10. meters) in 2.0 minutes. a) What is the period of its motion in seconds?

b) What is the object's speed in meters/second?

c) What is the object's centripetal acceleration in m/s2?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

Iwannasay c is the most accurate

The answer is  a.first and third quarters
