Question 2: Three forces act on a 1.0 kg object: F1 = -9.8 x N, F2 = 6.7 x - 3.2 y N, and F3 = -2.4 j N. The object moves from (0,0) to (5.0, 7.5 m). a) Find the net force on the object over the displacement. [-3. 1 x-5.6 y N] b) Find the acceleration of the object. [-3.1 x-5.6 y m/s2] c) If the final speed of the object is 2.0 m/s, find its initial speed. [13.9 m/s]
