Jack and jill are maneuvering a 3000 kg boat near a dock. initially the boat's position is < 2, 0, 3> m and its speed is 1.3 m/s. as the boat moves to position < 4, 0, 2> m, jack exerts a force of< -400, 0, 200> n, and jill exerts a force of < 150, 0, 300> n. what is final speed of the boat?

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
