What is the speed of an athlete who completed his one round along a circular path of diameter 120 m in 1 min?

Now, it is given that the time taken to complete one round of the circular track by the athlete = 40s. Thus, the speed of the athlete =200π40=5π m/s.

When an athlete runs on a circular path and reaches the starting point his displacement is?

Displacement will be zero. This is because the starting and stopping point of the athelete was same.

What is the distance covered by the athlete?

(a) Total distance covered by each athlete = 4 × 200 = 800 m. (b) As the line of finish is the same as the line of start, so displacement of each athlete = 0. (c) Motion of the athletes is non-uniform as the speed of the athlete will be changing at each point.

What is the distance Travelled by the athlete in the first 15 seconds?

Therefore, the average speed of the athlete is 6ms⁻¹ and the distance travelled by the athlete in the first 15 seconds is 120m.

What is the magnitude of distance and displacement of an athlete completes one lap in a race?

The displacement of the object is zero. It reaches at its initial position after one lap. Hence, in option (1) i.e. An athlete completes one lap in a race, the distance covered and the magnitude of the displacement are not the same.

What will be the work done if you are completing one round of circular track give support to your answer?

The work done on a body moving in a circular path is also zero. This is because, when a body moves in a circular path, then the centripetal force acts along the radius of the circle, and it is at right angles to the motion of the body. Thus, the work done in the case of moon moving round the earth is also zero.

What is the distance and displacement of a circular ground?

Displacement of object is equal to the length of the shortest path between the final and the initial points. Its direction is from the initial point to the final point. It is a vector quantity. For example, if a body moves along a circle of radius r and covers half the circumference, then displacement is given by s=2r.

What is the distance and displacement covered by a horse which runs on circular track of radius 7 meter after completing half the round?

The distance covered by the horse is the n2πr, wherer is the radius and n is the number of rounds completed by the horse. The Displacement of the horse after completing half round will be 2r.
