Q. At one instant, a mass (m = 2 kg) is at the location < 0.35, -0.47, 0 >m and attached to one end of a spring with a spring constant ks = 60 N/m and a relaxed length L0 = 0.22 m. The origin is located where the other end of the spring attaches to the ceiling.
Determine the net vector force acting on the mass.
