Three dogs are pulling on a bone with the following horizontal forces: F1 = 123 N [E] F2 = 172 N [E 20.0deg S] F3 = 154 N [S 60.0deg W] a Draw a horizontal free-body diagram of these forces on the bone. [1 mark] b) Determine the net force acting on the bone. [4 marks] c) If the bone has a mass of 1.4 kg, determine the acceleration of the bone? [1 mark] Answers should be in the form (number) (unit) [(direction)], for example 4.3 m [E], 5 km/h [S], 2.9 m/s*2 [W]. 2.7x10*3 m/s [N 56deg W], or 7.61x10*3 N [down]. Number should be to the correct Sig Figs, space between number and unit, and a space between units and direction (if required), direction in square brackets. There should be no curved brackets in your answers, Only use Scientific notation if the number number is 10 or larger, or less than 1
