1 Pretest: Unit 2 The figure shows three displacement vectors, which are labeled a 15m west, b 2.0m east and c 7.0m east. What is the magnitude and direction of the resultant vector found by adding a and b? A 13m west B. 13m easy C. 17m west D. 17m east​

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as
