Forces in 2D I) Two children pull a third child on a toboggan (shown from the top, assume up is north). Assuming that they pull on copes that are parallel to the ground determine the magnitude of the force exerted on the toboggan. 2) If the mass of the child and toboggan is 28 kg, what is acceleration? 3) A pack of five Arctic wolves are exerting five different forces upon the carcass of a 303-kg dead polar bear. A top view showing the magnitude and direction of each of the five individual forces is shown in the diagram at the right. What is the resultant force? 4) A force of 120. N [E30.ON] and 80.0 N [E40S] act on an object. a. Draw a vector diagram of the two original vectors b. Find the resultant of the two vectors. (Trig or Component method) c. What would a third force need in be to make the net force zero
