Exam 3: Kinematics in Two Dimensions; Vectors

A pilot drops a package from a plane flying horizontally at a constant speed. Neglecting air resistance, when the package hits the ground the horizontal location of the plane will

A player hits a tennis ball into the air with an initial velocity of 32 m/s at from the vertical. How fast is the ball moving at the highest point in its trajectory if air resistance is negligible?

A plane has an airspeed of 142 m/s. A 30.0 m/s wind is blowing southward at the same time as the plane is flying. What must be the heading of the plane in order to move directly eastward relative To the ground?
