2. 3. An object is thrown up and its vertical displacements is described by the equation - (4.9 m2) t² + (5.75 m²) t + 2m, where s is in meters and is in seconds. At what value/s of twill the object reach a vertical displacement of 3.52m (i.e., at s = 3.52m)? A rescue team is in a helicopter that is 650 feet in the air to deliver rations to the stranded residents. The angle of depression to the landing spot is 28°. How far is the landing spot from the point directly beneath the helicopter's current position?
