1. An object with a weight of 60 N is suspended by two lengths of rope from the ceiling. The angles that both lengths make with the ceiling are the same. The tension in each length is 40 N. Determine the angle that the lengths of ropes make with the ceiling. 2. The vector a is twice as long as the vector b. The angle between the vector is 25 and the magnitude of their cross product is 16.0. Determine |b|
