Two kids create a makeshift seesaw by setting a 4-m long uniform plank on a saw horse. The saw horse is 0.5 m to the left of the center of mass of the plank. The child of mass m1 = 48 kg sits at the left end of the plank. The child of mass m2 = 35 kg sits 1 m to the right of the center of mass of the plank. What is the mass of the plank?

A worker stands a distance
d = 0.325 m
from the left end of a plank as shown in the figure. The plank
is supported by three cords. Find the tension in each cord (in N).
Assume the plank is uniform, with length L = 2.00 m and
mass 29.5 kg, and the weight of the worker is 720 N. (Due to the
nature of this problem, do not use rounded intermediate values in
your calculations—including answers submitted in
WebAssign.)...

Question 3 In the figure, two identical, uniform, and frictionless spheres, each of mass 5.4 kg, rest in a rigid rectangular container. A line connecting their centers is at 45° to the horizontal. Find the magnitudes of the forces on the spheres from (a) the bottom of the container, (b) the left side of the container, (c) the right side of the container, and (d) each another. (Hint: The force of one sphere on the other is directed along the...
