Tutorial 2: Vector and translational kinematics.
1. Vector is 3.00 units in length and points along the positive x-axis. Vector is 4.00 units in length and points along the negative y-axis. Use graphical methods to find the magnitude and direction of the vectors (a) + and (b) - . [5.0 units at –53°, 5.0 units at +53°]
2. Determine the resultant of the following forces by the component method of vector addition: A = (200 N, 30.00); B = (300 N, 3300; and C = (400 N, 2500). [R = 519 N, 55.20 S of E]
3. Three horizontal ropes pull on a large stone stuck in the ground, producing the vector forces , , and shown in figure. Find the magnitude and direction of a fourth force on the stone that will make the vector sum of the four forces zero. [90.2 N, 256o]
4. A force of magnitude 6.00 units acts on an object at the origin in a direction =
