1. Two mobile containers, A and B, carries raw materials for concrete batching plant. The containers' motions are defined by their velocity vectors: for container A, A = 6i + 4k (km/hr) and for container B, B = -4i +7k (km/hr). What is the angle between the line of action (path) of both containers? Express your answer in units of degree. 2. Two cables A and B are attached to a hook. Cable A exerts a pull with a magnitude and direction defined by the vector A = 6i + 4k (kN). Cable B is also attached to the same hook where cable A is attached, cable B exerts a pull with a magnitude and direction defined by the equation B = -4i +7k (kN). What should be the magnitude of pull exerted at cable B such that the line of action of resultant force is along the positive z-direction (the resultant lies along the positive z-axis)? Express your answer in unit of kN.

Question
1. Two mobile containers, A and B, carries raw materials for concrete batching plant. The containers' motions are defined by their velocity vectors : for container A,
A = 6i + 4k (km/hr) and for container B,
B = -4i +7k (km/hr). What is the angle between the line of action (path) of both containers? Express your answer in units of degree.
2. Two cables A and B are attached to a hook. Cable A exerts a pull with a
magnitude and direction defined by the vector A = 6i + 4k (kN). Cable B
is also attached to the same hook where cable A is attached, cable B
exerts a pull with a magnitude and direction defined by the equation B = -4i +7k (kN). What should be the magnitude of pull exerted at cable B such that the line of action of resultant force is along the positive z-direction (the resultant lies along the positive z-axis)? Express your answer in unit of kN.
