An athlete completes one round of a circular track of radius 10 meter in 40 sec.the distance covered by him in 2min.20 sec.?
Time=2m and 20 seconds ( converts it into second)
s0 time in seconds = 140 seconds
now
v=w*r = 2*22/7*100
40 seconds = 2 * 22/7 *100
1 second = 2 * 22/7 * 100/40
140 second = 2 * 22/7 * 100/40 * 400
so, it gives = 2200 m
so the distnace is 2200 m
and the dispalcement is 200 m
What else can I help you with?
An athlet completes one round of a circular track of diameter 200m in 40s what will be the distance covered and the displacement at the end of 2 minutes 20s?
Distance covered - 2199m Displacement - 200m Distance covered - 2199m Displacement - 200m
Can a body have distance without displacement give an example?
Sure. As one car goes around a circle and as it completes one full rotation, then distance covered by the car is the circumference of the circle. But the displacement is Zero. So distance but no displacement.
What is the distance covered when a cyclist rides halfway around a circular track with the radius of 140M?
The distance covered by the cyclist when riding halfway around a circular track with a radius of 140 meters is equal to the circumference of the circle, which is 2 * π * radius. Therefore, the distance covered would be 2 * π * 140 = 880 meters.
An athlete completes one round of a circular track of diameter 200m in 40 seconds What will be the difference covered and the displacement at the end of 2 minutes 20 seconds?
Athlete covers 2pi radians in 40 s. So angular velocity = pi / 20 rad/s Hence the velocity = r w r = 100 m. So v = 5 pi m/s Hence the distance covered in 2 min 20 s ie 140 s = 700 pi metre. Displacement is the shortest distance between initial and final position In 140 s, 3 full rotation and one half rotation. So the he will be diametrically opposite. Hence the displacement is equal to 200 m ie diameter of the circular track.
How does momentum affect Long Jump?
In long jump, momentum plays a crucial role in propelling the athlete forward and increasing the distance covered. The greater the speed and body mass of the athlete during takeoff, the more momentum they can generate for the jump. This momentum helps the athlete maintain their velocity in the air and cover a longer distance.
What is the average speed at 20 seconds?
None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.
Is distance covered during nth second more than the distance covered in n seconds?
Distance covered in nth second means the distance covered in that particular second . It cannot be more than the distance covered in n seconds which means the distance covered in a total time of n seconds.
What is the instrument used to measure the distance covered by an athlete in the events like long jump?
A measuring tape.
How do you compute the average speed of an athlete?
To compute the average speed of an athlete, you need to divide the total distance they covered by the total time taken to cover that distance. The formula is: average speed = total distance / total time.
A athlete covers 200m in 40 secondsFind Displacament and distance covered at the end of 140 seconds?
Displacement is the direct distance from start to finish (straight line) so we can't determine this from the info given. The speed is 5m/s so after 140s 700m will have been travelled (5m/s x 140s)
Why are sand dollars circular?
Sand dollar's circular appearance is due to it's hard shell like structure called the Test that is circular. the test is covered by the spiny skin.
Is the distance covered by a body may be greater than a magnitude of the displacement?
yes,displacement is the shortest distance covered by a body,so distance covered by a body may be greater than the displacement.
