Answer 1

Answer:

displacement = 14 m

distance = 286 m

Explanation:

total time= 2*60 +10 =130 sec

therefore no. of revolutions = 130/20 =6.5

so 6 complete rounds and 1 half round

therefore displacement is equal to the diameter i.e. 14 m

now distance is 6*2*22/7*7 +22/7*7 = 286 m

Answer 2

Answer:

distance= 44m displacement=14m

Explanation:

here distance covered = circumference of circular track =

here distance covered = circumference of circular track = $2\pi \: r$

here distance covered = circumference of circular track = $2\pi \: r$22/7 × d

here distance covered = circumference of circular track = $2\pi \: r$22/7 × d22/7 × 14

here distance covered = circumference of circular track = $2\pi \: r$22/7 × d22/7 × 1444m

DISTANCE = 44m

if he takes 20 sec to complete one round,

if he takes 20 sec to complete one round, 2min and 10 sec = 130 sec

if he takes 20 sec to complete one round, 2min and 10 sec = 130 secat 120 sec he would have done 6 rounds... displacement =0

if he takes 20 sec to complete one round, 2min and 10 sec = 130 secat 120 sec he would have done 6 rounds... displacement =0but time is 130... 120 +10

if he takes 20 sec to complete one round, 2min and 10 sec = 130 secat 120 sec he would have done 6 rounds... displacement =0but time is 130... 120 +106 and 1/2 rounds.... displacement = diameter = 14m
