Answer» a cyclist completes 4 rounds in 16 minutes around a circular track with UNIFORM speed of 6.28 m/s, To FIND : the radius of that track A)120m B)180m C)210 m D)240mSolution:Distance covered in one ROUND = circumference = 2π(radius)π = 3.14 , radius = r mHence Distance covered in one round = 6.28r mDistance covered in 4 rounds = 4 * 6.28r mSpeed = 6.28 m/sTime = 16 MINS = 16 * 60 = 960 secDistance = Speed * Time=> 4 * 6.28r = 6.28 * 960=> 4r = 960=> r = 240 mradius of that track is 240 mLearn More:If a body is in a uniform circular motion with a speed of 2 m/s having ... brainly.in/question/18231940 A cycle is moving with the speed of 5m/s on the circular track of ... brainly.in/question/13135773
