Abody covers one revolution around a circular park of circumference 176m in 4 minutes. find the displacement of the body after 6 minutes

Total distance around the track is 176m.

Speed of the body = total distance covered/total time taken

                                 = 176/4

                                 =44metres/min

Find the distance covered in 6 minutes:

                           if 1 min= 44m

                           then 6 min=(44X6)/1 =264

There the distance covered around the track from starting point = 264-176

                                                                                                             =88 metres

This corresponds to distance around half the track, which means displacement corresponds to 180 degrees

Hence, the displacement distance is the diameter.

total distance around the track= 176m

Circumference=Xdiameter176=22/7 XD

                                                                       D=176X7/22

                                                                     =56 (therefore the displacement is                                                                                            56meters)
