Pushing a Block and a Wedge 0 points possible (ungraded) In the following problem, you are asked to: i) Define the system and the environment: Identify which objects - the environment - interact with the object of interest - the system. Justify your choice of system: would a different choice also work? If not, why not? If so, why is the choice you made better? ii) Describe the interactions and the resulting forces: Identify the forces exerted on the object of interest by the other objects. iii) Draw the free body diagram of the object: Make sure that each force arrow is labeled with two subscripts - who is exerting the force and on whom is the force being exerted. The length of the arrows should represent qualitatively the magnitude of the force. a) c) M m 0 a F M m 0 A block of mass m rests on a frictionless wedge which has a mass M and whose surface makes an angle to the horizontal as Calculator
