You are standing on the edge of a ravine that is 17.5 m wide. you notice a cave on the opposite wall whose ceiling is 7.3 m below your feet. the cave is 4.2 m deep, and has a vertical back wall. you decide to kick a rock across the ravine into the cave. what initial horizontal velocity must you give the rock so that the rock barely misses the overhang? the acceleration of gravity is 9.8 m/s 2 .

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
