Two students are on a balcony a distance h above the street. The first student throws a ball vertically downward at a speed Voi at the time, the second student throws a ball vertically upward at the same speed. Answer the following symbolically in terms of vo, g, h, and t. (a) Write the kinematic equation for the y-coordinate of each ball. (Let up be positive.) 1 2 ball 1 1 ball 2 Y2= -Vo²2 (b) Set the equations found in part (a) equal to height 0 and solve each for t symbolically using quadratic formula. What is the difference in the two balls' time in the air? (Remember that t must always be a positive quantity.) t2 - t = (c) Use the time-dependent kinematics equation to find the velocity of each ball as it strikes the ground. ball 1 v = V vó+ 2gh V+ 2gh ball 2 V2 =
