Question

If a cyclist takes 1minute to complete half of the revolution on a circular path of 12-m radius, then the average velocity of the person is _________

Answer 1

$\huge{ \underline{ \underline{\mathrm{ \red{♡Answer♡}}}}}$

After half revolution, the cyclist will be on the opposite side of the diameter from the point where he started

After half revolution, the cyclist will be on the opposite side of the diameter from the point where he startedSo his displacement = diameter = 2×120m=240m

After half revolution, the cyclist will be on the opposite side of the diameter from the point where he startedSo his displacement = diameter = 2×120m=240mtime taken is 1min=60s so average velocity v=

After half revolution, the cyclist will be on the opposite side of the diameter from the point where he startedSo his displacement = diameter = 2×120m=240mtime taken is 1min=60s so average velocity v= 60

After half revolution, the cyclist will be on the opposite side of the diameter from the point where he startedSo his displacement = diameter = 2×120m=240mtime taken is 1min=60s so average velocity v= 60240m

After half revolution, the cyclist will be on the opposite side of the diameter from the point where he startedSo his displacement = diameter = 2×120m=240mtime taken is 1min=60s so average velocity v= 60240m

After half revolution, the cyclist will be on the opposite side of the diameter from the point where he startedSo his displacement = diameter = 2×120m=240mtime taken is 1min=60s so average velocity v= 60240m =4m/s

After half revolution, the cyclist will be on the opposite side of the diameter from the point where he startedSo his displacement = diameter = 2×120m=240mtime taken is 1min=60s so average velocity v= 60240m =4m/sSo, the correct answer is '4m/s'.

Answer 2

Answer:

After half revolution, the cyclist will be on the opposite side of the diameter from the point where he started

So his displacement = diameter = 2×120m=240m

time taken is 1min=60s so average velocity v=

60

240m

​

=4m/s

So, the correct answer is '4m/s'.
