PROBLEMS on of the force P.given that its magni- 1.40 Obtain the rectangular representati tude is 30 lb. s0° 30° Figure P1.40 1.41 The length of the position vector r is 240 mm. Determine the rectangular components of (a) r; and (b) the unit vector directed from O toward A. 1.42 Determine the rectangular components of the 560-lb force. Show the com- ponents on a sketch. 1.43 The coordinates of points A and B are (-3,0, 2) ft and (4. 1, 7) ft, respec- tively. Determine (a) the distance between A and B; and (b) the rectangular rep- 40° y resentation of the unit vector directed from A toward B. 50° 1.44 The slider travels along the guide rod AB with the velocity v 8 m/s. Determine the rectangular representations of (a) the unit vector directed from A toward B; and (b) the velocity vector v. Figure P1.41 3 ft Help with 1.41 ,thank you
