A circular track has a circumference of 3140 m with AB as one of its diameter. A scooterist moves from A to B along the circular path with a uniform speed of 10 m/s. Find (a) distance covered by the scooterist, (b) displacement of the scooterist, and (c) time taken by the scooterist in reaching from A to B.
Part (a) Step 1: Distance Calculation The distance covered is the actual path length between point A and B. Distance covered, D= Half of the circumference =23140=1570m Part (b) Step 2: Displacement Calculation Displacement is the shortest distance between the initial and final points. Here, the shortest distance between A and B is the diameter AB. d=AB Circumference =3140=2πR ⇒ R=500m ∴AB=2R=1000m Displacement, d=1000m Part(c) Step 3: Time Calculation Time taken by the scootrist in reaching from A to B: t=SpeedDistance =10m/s1570(m) ⇒t=157s
