Question

An athlete completes a round of a circular track of diameter 200m in 20 seconds calculate the distance travelled and the magnitude of displacement of the rotation

Answer 1

Answer:

a) Time taken to complete 1 rounds = 20 s

a) Time taken to complete 1 rounds = 20 s1 minute 10 seconds = 70 seconds

a) Time taken to complete 1 rounds = 20 s1 minute 10 seconds = 70 secondsNumber of rounds that can be completed in 70 seconds = 70/20 = 3.5 rounds

a) Time taken to complete 1 rounds = 20 s1 minute 10 seconds = 70 secondsNumber of rounds that can be completed in 70 seconds = 70/20 = 3.5 roundsDistance travelled = circumference of circle = 2 pie r

a) Time taken to complete 1 rounds = 20 s1 minute 10 seconds = 70 secondsNumber of rounds that can be completed in 70 seconds = 70/20 = 3.5 roundsDistance travelled = circumference of circle = 2 pie rDiameter= 200

a) Time taken to complete 1 rounds = 20 s1 minute 10 seconds = 70 secondsNumber of rounds that can be completed in 70 seconds = 70/20 = 3.5 roundsDistance travelled = circumference of circle = 2 pie rDiameter= 200Radius= 100

a) Time taken to complete 1 rounds = 20 s1 minute 10 seconds = 70 secondsNumber of rounds that can be completed in 70 seconds = 70/20 = 3.5 roundsDistance travelled = circumference of circle = 2 pie rDiameter= 200Radius= 100Distance travelled = 2 *3.14*100*3.5 = 2198

a) Time taken to complete 1 rounds = 20 s1 minute 10 seconds = 70 secondsNumber of rounds that can be completed in 70 seconds = 70/20 = 3.5 roundsDistance travelled = circumference of circle = 2 pie rDiameter= 200Radius= 100Distance travelled = 2 *3.14*100*3.5 = 2198Displacement = Shortest distance travelled

a) Time taken to complete 1 rounds = 20 s1 minute 10 seconds = 70 secondsNumber of rounds that can be completed in 70 seconds = 70/20 = 3.5 roundsDistance travelled = circumference of circle = 2 pie rDiameter= 200Radius= 100Distance travelled = 2 *3.14*100*3.5 = 2198Displacement = Shortest distance travelled3 rounds = Displacement = 0 , as initial and final point is same.

a) Time taken to complete 1 rounds = 20 s1 minute 10 seconds = 70 secondsNumber of rounds that can be completed in 70 seconds = 70/20 = 3.5 roundsDistance travelled = circumference of circle = 2 pie rDiameter= 200Radius= 100Distance travelled = 2 *3.14*100*3.5 = 2198Displacement = Shortest distance travelled3 rounds = Displacement = 0 , as initial and final point is same.Now, 0.5 = half round = diameter of ground = 200 m

a) Time taken to complete 1 rounds = 20 s1 minute 10 seconds = 70 secondsNumber of rounds that can be completed in 70 seconds = 70/20 = 3.5 roundsDistance travelled = circumference of circle = 2 pie rDiameter= 200Radius= 100Distance travelled = 2 *3.14*100*3.5 = 2198Displacement = Shortest distance travelled3 rounds = Displacement = 0 , as initial and final point is same.Now, 0.5 = half round = diameter of ground = 200 mThus, displacement = 200 m.
