two boys with same height of 1.2 m are flying kites at the same place. One of them takes a 25 m long thread which makes an angle of 45° with the horizontal line whereas the next takes away 35 m long thread which makes an angle of 60° with the same horizontal line.

Alake near the arctic circle is covered by a 222-meter-thick sheet of ice during the cold winter months. when spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. after 333 weeks, the sheet is only 1.251.251, point, 25 meters thick. let s(t)s(t)s, left parenthesis, t, right parenthesis denote the ice sheet's thickness sss (measured in meters) as a function of time ttt (measured in weeks).
