1) Two forces act on a 150 kg mass, 50 N [W] and 200 N [S 45. W]. Calculate the net force (magnitude and direction) and acceleration of the mass. Include a free body diagram. [5] 2) Given F, = 80 N [E 250 N] and F2 = 170 N [S 75. W], calculate the force (magnitude and direction) of F. needed so that F, + F: + F, is zero (net force = zero). Include a free body diagram. [5] 1) One day two students decided they did not want a physics lesson and skipped class. On their walk they found a car stuck in the mud. Since they pay attention in class they know it is best to push rather than pull the car. Student one pushes 500 N [S 25* W] and student two pushes 750 N [N 25 W]. The force of friction due to the mud is 200 N [E]. a) Draw a free body diagram labelled. [2] b) Calculate the net force (direction and magnitude). [4] c) The car's mass is 500 kg. Calculate the car's acceleration (direction and magnitude). [
