Determine the momentum of a system of the two objects. One object, m1, has a mass of 1.4 kg and a velocity of 9 m/s towards the south and the second object, m2, has a mass of 2.6 kg and a velocity of 10 m/s towards the north. What is the magnitude and direction of the momentum of the system? Please provide an explanation, random answers will be reported thank you.​

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?
