A) The students draw the following Free Body Diagram for the situation. Is thế Freë Body Diagram correct? Check the directions of all of the forces and make sure that the students didn't miss any forces. Fix any mistakes that you find. B) The students next wrote the following statement for Newton's 2nd Law for the system: Fn 2Mg T EF system = (2M + M)a =F +FN- 2Mg - T +T – Mg . Is this correct? Fi: mistakes that the students made and explain why they were mistakes. C) A second student noticed that this equation can't be solved for Tensi Instead, they wrote the following equation for Block 2M: EF M Block 2M = 0 = luded thatT must be 40N Is this correct? If not, explain why not. Mg
