Three F forces 1 = (2.00î + 2.00ĵ) N, F2 = (−5.00î− 3.00ĵ) N and F3 = (4.50î) N act on a body, initially at rest, producing an acceleration equal to 3 , 60m s 2 ⁄. (a) What is the direction of the acceleration vector in relation to the x-axis> 0? (b) What is the body mass? (c) What is the speed of the body after 10.0s? (d) What are the components of the velocity vector after 10.0s? Answers: (a) θ ≅ 326.3 °; (b) m = 0.500kg; (c) v = 36,0m⁄s and (d) vx = 30,0m⁄s and vy = −20,0m⁄s.
