7. Spring A will stretch vertically by 20.0 cm when it has a 1.00 kg rnass hanging from it. Spring B will stretch vertically bv 50.0cm when it has a 1.00 kg mass hanging from it. 3] Draw a free body diagram for Spring A and include all relevant forces and values. Draw a free body diagram for Spring 8 and include all relevant forces and values. In} Calculate the spring constant of A. c} Calculate the spring constant of B. d} Suppose that the 1.00 kg mass is hanging from the end of A, which is hanging from B. Assuming that the mass of the springs is negligible, calculate the total amount of stretching. e} Calculate the spring constant of the system in part {d}
