RECITATION PROBLEM 1 (05/13/15)

This problem is due Monday, 05/18/15 A 0.15kg ball is launched from the ground and moves under the in�uence of gravity as well

as a second force from the wind. The force of wind is assumed to be constant, but neither the magnitude nor the direction are known. The object's trajectory is plotted below, and several points from the trajectory (marked on the plot) have been tabulated. What is the force of the wind on the ball (in magnitude/direction form).
