While Juliet was watching Romeo ran at a speed of 3.3 m/s straight off the end of a diving board that is 3 m above the water. How long was he airborne before he hit the water?

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
