answer only red ones

For significant injury, a body part such as a leg must be suspended. This must occur in such a way as to not put undue pressure on another body part. Consider the Image to the right. Determine the weight required to suspend the 220 N cast as well as the angle required to keep it in suspension. ION 170 N X 18 2 7 5/ 10 points In the situations to the right, the guy can push or pull his girlfriend on the sled. The combined weight of the girl + sled is 630. N. According to theory, it takes more force to start an object in motion than it takes to keep it In motion. Therefore, there is a critical applied force required to overcome static friction and to start the girl's motion (a] If the coefficient of static friction is 0.140, find this critical applied force for both cases fle he will have to push or pull will a force greater than or equal to the amount you find to start her In motion Hint: All components of this problem are similar, Keep In mind that you will simply need to make modifications to the original equations and force tables of part (al for subsequent parts Case (al, Push 11IN Case (b). Pull 94.2N bi Which case requires more force? (Simply Input a or b] Does this imake sense? (c) in which case is the Normal force greater than the gravitational forcet (Simply Input a or by (d) If the coefficient of kinetic friction is 0. 100, and he can push or pull with a force of 120, N, find her acceleration in both cases Case (al, Push 054m/52 Case (bi, Pull 073 mA*2 (e) Once they have traveled 2 00 m, he begins to get tired and decreases his applied force. At that point. just before he does, what is her velocity in both cases?Case tal, Push: 146 ma Case [b), Pull 17m/ (1) How much force must he continue to apply to keep her moving at this constant velocity, in both cases?Case fat, Pushy 772N Case (b), Pull: GILBN 'd Compare the forces from let to the forces from tal, Do these results agree with the theory concerning static Game: kinetic forces Yes Consider why or why not? And consider this the next time you must move a heavy object. Will you push or pull pull Feedback Based on answering incorrectly
