Decribe the relationship between kinetic energy and speed

Every moving object has kinetic energy.

The kinetic energy a moving object has is

(half of its mass)

multiplied by

(the square of its speed).

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)
