Question

when athlete runs a circular track whose radius is 50 M without constant speed it takes 50 second to reach point B and from starting point a find the distance covered the speed the displacement

Answer 1

Answer :

Part A :

distance = πr = 50π = 157.14 m

Part B 

Displacement =  2r = 2 x 50 = 100 m 

Part C 

distance / time = speed = 157.14/50 = 3.14 m/s or π m/s

Answer 2

Answer:

Part A :

distance = πr = 50π = 157.14 m

Part B

Displacement =  2r = 2 x 50 = 100 m

Part C

distance / time = speed = 157.14/50 = 3.14 m/s or π m/s
