Draw a free body diagram for both parts of this question, also include the formulas Fnet=ma and Fnet = F1 + F1, and any other formulas used:
A large football player student (1.0 x 102 kg) applies a 6.0 x 102 N force to another equally burly student (1.0 x 102 kg) sitting on a sled (13.2 kg). If sliding friction and air resistance (drag) is 99.5 N, find the acceleration of the sled. In addition, how much force does the football player need to apply to the ground to accomplish this feat? Remember, he needs to get himself moving too!
