Part B You place the spring vertically with one end on the floor. You then drop a book of mass 1.10 kg onto it from a height of 0.500 m above the top of the spring. Find the maximum distance the spring will be compressed. Take the free fall acceleration to be 9.80 m/s2.

Explanation / Answer

Conserving energy

Initial potential energy=final energy of spring

Mgh=0.5kx*x

We know M=1.1 kg

h=0.5m

K=1700

Putting values we got

x=0.079 m=7.9 cm
