Question

A body completes one round of a circular path of radius 14m in 10 seconds. Calculate its average speed and average velocity at the end of one round.

Answer 1

Average speed = 8.8 m/s

Average velocity = 8.8 m/s

Step-by-step explanation:

From the question,

Avearge speed = 2πr/t................ Equation 1

Where r = 14 m, t = 10 s

Constant π = 22/7

Substitute this value into equation 1

Average speed = 2(22/7)(14)/10

Avearge speed = 8.8 m/s.

For a body moving in circular motion, The average speed and average velocity are equal.

Hence,

Average speed = 8.8 m/s

Average velocity = 8.8 m/s
