Answer:
The distance will be 5πr and the displacement will be πr.
Step-by-step explanation:
The distance travelled in first 20 seconds is 2πr.
speed=distance/time
=2πr/20
=πr/10
so the distance travelled in 50 seconds is
distance= 50*πr/10
=5πr
Displacement is the shortest distance Between the initial and final position. so here the displacement will be πr.
