Question
Two springs have the same equilibrium length but different spring constants. They are arranged as shown in the figure, then a block is pushed against them, compressing both by 6 cm.
With what net force do they push back on the block? Answer in Newtons
Explanation / Answer
THe net force they push back on the block is
F = (k1 + k2)x
= (12.0N/cm + 5.4N/cm)(6.0cm)
= 104.4N
