# Supply plane#

A supply plane needs to drop a package of food to scientists working on a glacier in Greenland. The plane flies 140$$m$$ above the glacier at a velocity of 180 $$\hat\imath$$ $$m/s$$. The horizontal distance between the plane and the drop site is $$R$$ at the time the package is released from the plane. For this question, assume that $$-\hat\jmath$$ is downward.

## Part 1#

What value of $$R$$ is required to ensure that the package arrives on target? Neglect air resistance.

Please enter in a numeric value in m.

## Part 2#

What is the acceleration vector of the package after it has fallen a vertical distance of 80$$m$$?

Please enter in a numeric value in $$m/s^2 \ \ \hat\jmath$$.

## Part 3#

What is the velocity vector $$\hat\imath$$ ($$V_x$$) of the package after it has fallen a vertical distance of 80$$m$$?

Please enter in a numeric value in $$m/s \ \ \hat\imath$$.

## Part 4#

What is the velocity vector $$\hat\jmath$$ ($$V_y$$) of the package after it has fallen a vertical distance of 80$$m$$?

Please enter in a numeric value in $$m/s \ \ \hat\jmath$$.
