Question

3) A 5kg block is hung from a spring. When the block is attached, the
spring stretches 8cm from its original length. If another 10kg is
added to the spring, how far will the spring stretch?

Answer 1

Answer:

24cm

Explanation:

Use Hooks Law; F=kx; F=Force, k=stiffness of the spring, x=distance.

k=F/x ; 5(9.8)/8 =6.125 N/cm

x=F/k 15(9.8)/6.125 = 24cm
