A 0.50 kg mass is attached to a spring with spring constant k=43.8 N/m as shown. Suppose the mass is pushed upward, so that it rises past the spring’s unstretched position, compressing the spring. Calculate the net force on the mass when the spring is compressed 3.7 cm. Include a free-body diagram.

mg + k x

0.50 * 9.81 + 43.8 * 0.037
The answer---------> 6.5256<---------The answer
Is it accelerating ?
If not someone is pushing upward with that same force magnitude and the net force is zero.
