1. For the vectors: A = 71 + 2j + 4k B = 41 - 3 j +5k Determine the following: a. A . B b. A x B C. | A| , |BI d. a , b e. 0, the angle between A and B 2. Convert the following vectors to unit vector notation: A = 3.60 m at 70 above the positive x axis. B = 2.4 m at 30 below the negative x axis. 3. Suppose the function for acceleration was found to be 3t + 4 m/s2. What would be the functions for instantaneous Velocity and Position
