Answer : F = 9800 N
Explanation :
It is given that,
The spring constant for the industrial scale at the junkyard, k = 39,200 N/m
Displacement of spring, x = 25 cm = 0.25 m
According to Hooke's law, the force applied on spring is given by the following relation :
F = -k x
Negative sign shows the force is applied in opposite direction.
[tex]F = -39,200\ N/m\times 0.25\ m[/tex]
So, [tex]F=-9800\ N[/tex]
[tex]|F|=9800\ N[/tex]
Hence, this is the required solution.
