Please help me with these two questions Draw a sketch and also a good FBD to identify the relevant forces doing work.Pay attention to the units and positive or negative value of the quantities.1. A football player pushes a tackling dummy forwards at a constant 0.85 m/s for 11 m using7150 J of energy. The tackling dummy has a mass of 120 kg.a) Find the force the football player exerts.b) What is the frictional force the dummy exerts?c) What work is done by friction as the dummy is slid along the field for 11 m?d) Is the mass necessary for this question? If not, what force question could be asked thatwould require the mass of the dummy?2. A person pushes on a hockey puck with their stick at an angle so the vertical force is 22 N[down] and the horizontal force is 45 N [forward]. Assume the ice is frictionless.a) What is the actual force the hockey player transmits to the puck?b) What is the work done by the person pushing the hockey stick if they push the puck for 3.0s as it moves with a constant velocity of 22 m/s [forward]?c) What is the significance of the fact that both the horizontal force and motion are bothforwards?
