Question
A 6.3kg mass hanging from a spring scale is slowly lowered onto a vertical spring, as shown.
A 6.3kg mass hanging from a spring scale is slowly lowered onto a vertical spring, as shown. The scale reads 17N when the lower spring has been compressed by 2.5cm . What is the value of the spring constant for the lower spring? Express your answer to two significant figures and include the appropriate units. At what compression length will the scale read zero? Express your answer to two significant figures and include the appropriate units.
Explanation / Answer
K=F/x=17/0.025=680N/m
compression length=0 when force=0
