Consider a circular irrigation system that has a maximum length of 200 m from the central pivot to the end of the arm. Several sprinklers have been placed for the irrigation of the land, each of them installed at 3.6 m from each other until reaching 54 m at the end from the central pivot. If you only want to irrigate one-quarter of the total circumference of the land, how far do the first and the last sprinkler travel to cover that stretch?

s1= 7. 798 m, s2= 93.654 m

s1= 5.655 m, s2= 84.823 m

s1= 6.893 m, s2= 76. 924 m

in a fun fair there is a ferris wheel and when this rotates 270° it stops. If its journey took 12 seconds. What was its angular velocity?

w= 0.628 rad/sec

w= 0.3925 rad/sec

w= 0.2985 rad/sec
