2. Florence, who weighs 440 N, stands on a bathroom scale in an elevator. What will she see the scale read when the elevator is decelerating while moving downward at 1.65 m/s²?(g = 9.8 m/s²)3. Four blocks, with masses m1 = 5.20 kg, m2 = 4.20 kg, m3 = 7.80 kg, and m4 = 7.30 kg, are pulled on a horizontal frictionless surface by a 35.0 N force that makes a 39 o angle (θ) with the horizontal (see figure). What is the magnitude of the tension between the m3 and m4 blocks?
