Two students are on the roof of a building 29.4 m above the street. One student throws a rock vertically downward at 4.9 m/s. At the same time, the other student throws a ball vertically upward at 4.9 m/s. The second ball misses the roof on its way down. a) Calculate the difference in the time the rocks spend in the air.
b) Calculate the velocity of each rock as it strikes the ground.
c) Calculate the distance between the rocks 0.5 seconds after they are thrown.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
