Phy 131 - Assignment 2 A. 1. 2. (The question does not say that F should be in component form. I just left it that way because it’s easiest. But if you gave the answer as 5.59 N at 63.4o, that’s ok too.) B. 1. No, never. The magnitude of a vector is just how “long” it is, regardless of its direction. (Similar to the absolute value of a scalar, hence the use of the same symbol.) 2. Displacement = 0. Displacement is a vector, so you add the displacements like this: (The resultant drawn from where you started to where you ended up is zero.) Distance traveled = 6 m. Distance is a scalar, so you add the distances like this: 2 + 1 + 2 + 1 = 6. 3. C. D. E. F. 1. a. No, b. No, c. yes, d. no. Velocity has a direction; the other three things do not. 2. Magnitude: a Direction: 5 .5 2 arctan 2.6 2 2. 6 5 .5 6.08 m/s2 25.3
