Question

Calculate the distance and displacement if a person runs along a circular track of
radius 10 m and completes one round in 10 minutes. Also, calculate his speed and
velocity.

Answer 1

Answer:

given radius = 10m , distance covered in 10 minutes = one round

one round is equal to circumference of the track

of 10 m radius

=> 2×pi×r

=> 2 × 22/7 × 10

=> 62.86 m

2. displacement in one round = 0 [ since he reaches the starting point after one round ]

1. distance = 62.86 m

3. speed = distance/time

=> 62.86/10 = 6.286 m/minute

=> 6.286/60 = 0.105 m/sec

4. velocity = displacement/time

=> 0/10×60 = 0
