While having a water balloon fight in the lobby of a hotel, Ruth and Lauren both throw water balloons off of the 3rd floor balcony, 15 m off the ground. Ruth tosses her ball downward at 15 m/s. Lauren tosses her balloon upwards at 15 m/s. The balloons both free-fall to the ground. VIS/5 Which Balloon hits the ground going faster? Support your answer with calculations. a.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
