1. A particle is moving in a circle of diameter 5m. Calculate the distance covered and thedisplacement when it completes 3 revolutions.2. A body travels a distance of 15m from A to B and then moves a distance of 20m atright angles to AB. Calculate the total distance travelled and the displacement.3. An object is moving in a circle of radius 'r'. Calculate the distance and displacementa. When it completes half the circleb. When it completes one full circle.. An object travels 16m in 4s and then another 16m in 2s. What is the average speed ofthe object?• Vishnu swims in a 90m long pool. He covers 180m in one minute by swimming fromone end to the other and back along the same straight path. Find the average speedand average velocity of Vishnu.In a long distance race, the athletics were expected to take four rounds of the tracksuch that the line of finish was same as the line of start. Suppose the length of thetrack was 200m.a. What is the total distance to be covered by the athletics?b. What is the displacement of the athletics when they touch the finish line?c. Is the motion of the athletics uniform or non-uniform?d. Is the displacement of an athletic and the distance covered by him at the end of the race equal?7.Starting from stationary position Bhuwan paddles his bicycle to attain a velocity ofor 6m/s in 30th.then he applies brakes such that the velocity of bicycle comes down to 4m/s in the next 5s. calculate the acceleration of the bicycle in both the cases ​
