1. For the following vectors: C = -5i +3j + 2km. a) Find A + B -C-A 2. Find the Magnitude of A from above. 3. Two forces act on an object. F₁: = 4.0i+2 j. Calculate the total force (F= F₁+F₂) in vector form for the following forces. Assume Force is in Newtons. b) F₂ = 3.0i+6 j a) F₂ = -5.0 i c) F₁ = 5.0 i + 3j A = 3i - 6j m, B = 8i +3j m, c) Find B (b) Find A - C + B (20) 4. A rock is thrown with initial velocity V = 35 m/s. Find initial velocities V and V, for the angles shown. Answers will be in m/s) a) 25 deg (31.7, 14.8) b) 40 deg (26.8, 22.5) c) 75 deg (9.1, 33.8) d) 135 deg (-24.7, 24.7) 5. Use the vectors shown to solve the problems: A = 2i - 6j B = 4i +2j, C = -5i + j + 3k. a) C B (-18) b) A + B d) a (b + c) (-20) c) B. B
