Question

calculate distance and displacement when a body moving on a circular path having radius 7 cm covers two one by two rounds

Answer 1

Answer:

Explanation:

circumfrence of a circle=distance covered

therefore; 2 x 22/7 x 7 = 44cm ( 1 round )

therefore for 2 and a half rounds = 44 x 1/2=22

                                                         = 44 x 2= 88

:- 88 is the distance covered

displacement of 2 rounds = 0

and the other half round = 7cm
