Question

ABC is a triangular traffic island with each side 20m in length. A cyclist riding his cycle at uniform speed starts from A and moves along the sides of the traffic island. If he takes one minute to complete one round , find :
A) :The speed of the cyclist
B) :The distance travelled by the cyclist and his displacement at the end of 5 minutes.
C) :The displacement of the cyclist at the end of 70seconds and 100 second .​

Answer 1

Answer:

Explanation:

speed of the cyclist=distance travelled by him/time taken by him to complete one round

so speed of cyclist=60m/60s=1m/s

distance  travelled by the cyclist to complete one round=20m+20m+20m=60m

displacement at the end of 5 minutes=0m

displacement of cyclist at the end of 70 seconds=10m

displacement of cyclist at the end of 100 seconds=20m

Answer 2

Explanation:

same as that posted above but displacement in 100m should be = 40 m
