A man of mass m1 = 70.0 kg is skating at v1 = 8.00 m/s behind his wife of mass m2 = 50.0 kg, who is skating at v2 = 4.00 m/s. Instead of passing her, he inadvertently collides with her. He grabs her around the waist, and they maintain their balance. (b) Is the collision best described as elastic, inelastic, or perfectly inelastic? (c) Why? (d) Write the general equation for conservation of momentum in terms of m1, v1, m2, v2, and final velocity vf. (Do this on paper. Your instructor may ask you to turn in this work.) (e) Solve the momentum equation for vf. (Use the following as necessary: m1, v1, m2, v2. Do not substitute numerical values; use variables only.) vf (f) Substitute values, obtaining the numerical value for vf, their speed after the collision. vf, couple m/s vf, man m/s vf, wife m/s

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 Β΅c of charge distributed uniformly along its length, and the other carries - 2.50 Β΅c 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?
