Question

A lawn sprinkler is constructed in such a way that d /dt is constant, where ranges between 45° and 135°. The distance the water travels horizontally is      x = v2sin2/32 , 45° ≤ ≤ 135° where v is the speed of the water. Find dx/dt and explain why this lawn sprinkler does not water evenly. What part of the lawn receives the most water?

= 105°
= 75°
= 135°
= 45°
