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:

displacement will be zero

distance 62.8 m

velocity will be zero speed will be 6.28m/min

Explanation:

hope it helps

Answer 2

Answer:

Distance traveled by him is equal to the perimeter of the circle i.e., 2πr = 2 × π × 10 m ≈ 62.83 m

Displacement will be zero as the person has completed one round and returned to the same position as he was before.

Hence, velocity (displacement/time) also becomes zero, as displacement is zero.

Now, speed will be distance/time, so speed is 2πr/600 m/s ≈ 0.1 m/s
