Question

2. A student runs around a circular track that is 1000m in length in a time of
30 min. What is the average speed and average velocity of the student ​

Answer 1

Answer:

Radius of lap = 100m

Circumference =2πR=200π=628m

time taken to cover one lap = 62.8s

Hence average speed =

62.8

628

=10ms

−1

Average velocity = 0 as the inital and final positions are same (after completing a lap) (displacement = 0)
