Two students are on a balcony a distance h above the street. One student throws a ball vertically down-ward at a speed v0: at the same time, the other student throws a ball vertically upward at the same speed. Answer the following symbolically in terms of v0, g. h, and t. (a) Write the kinematic equation for the y- coordinate of each ball. (b) Set the equations found in part (a) equal to height 0 and solve each for t symbolically using the quadratic formula. What is the difference in the two balls' time in the air? (c) Use the time-independent
