stion 2 of 8
<.
A delivery person carries a stack of three boxes labeled 1, 2, and 3, with box 3 on the bottom of the stack and box 1 on the
top. The masses of boxes 1, 2, and 3 are m1 1.15 kg, m2
2.34 kg, and m3 = 6.80 kg, respectively. The delivery person
places the stack of boxes on an elevator floor, which then accelerates upward with a magnitude of a =
0.96 m/s.
Let g 9.81 m/s denote the acceleration due to gravity, and let the positive y-direction be upward.
Calculate the contact force F2 that box 1 exerts on box 2
during the acceleration.
