Question

At Mike’s old college, the clever (and rascally) students had a pastime called “funnelation”: the use of a huge slingshot made from a funnel and rubber tubing to launch water balloons over the roof of one dorm into the courtyard of another. Suppose that Mike’s “funnelator” gives all water balloons an initial velocity v0 of 40.0 m/s (almost 90 mph!). Mike aims his slingshot at an angle of 60.0˚ above the horizontal, on level ground, and fires one balloon. (Ignore air resistance for this entire problem. Assume that the water balloon is launched from the origin, and that the +y-direction is upward. Graph the projectile’s HORIZONTAL components of position, velocity, and acceleration, from launch to landing:
