Question

A cyclist is moving at a uniform speed of 20 m per second for 30 second hidden stop pedaling the and stop in next 10 second calculate the total distance travel and average retardation

Answer 1

$\huge\bold \red{soution}$________________________________

_______________________________________

average acceleration =change in velocity time ⌚

in this case time =40s

change in velocity =20

acceleation =-20/40

=0.5m/s

average relation is 0.5m/s

Thanks

Answer 2

average acceleration =change in velocity time

in this case time =40s

change in velocity =20

acceleation =-20/40
