1.What are the forces acting on the block when it is hanging freely from the spring scale? What is the net force on the block? What are the magnitudes of each of the forces acting on the block? Explain.
So for the above question, Im confused how I would find the magnitude specfically?
I would also like to mention , the weight of the block on the scale is 55.8 newtons
If the block has any unbalanced forces acting on it, it will move. SInce it is hanging and not moving it has no net force, it will have a downward force of
f=ma this force will exactly equal the upward spring force of kd (k = spring constant d = stretch of spring).
One is a downward force (say 'negative') the other is an upward force (say 'positive') but the MAGNITUDES are equal and they balance/cancel each other...so there is no net force acting on the block (net force = 0)
Addition: 55.8 newtons downward and 55.8 newtons upwards are the forces acting on the block. NET force = 0
