Energy is not conserved.
momentum is conserved.
momentum putty=momentumclump
.07*5.8=(.4+.07)Vi solve for Vi upward.
Vi^2=(.4+.07)g h solve for h.
A 0.400 kg block of wood hangs from the ceiling by a string, and a 0.0700 kg wad of putty is thrown straight upward, striking the bottom of the block with a speed of 5.80 m/s. The wad of putty sticks to the block.
Is the mechanical energy of this system conserved?
yes or no
(b) How high does the putty-block system rise above the original position of the block?
____ cm

What’s up g. I’m not sure where you got this from (Vi^2=(.4+.07)g h solve for h.).
Mgh is used to compute potential energy, so I don’t understand why you set it equal to Vi^2. Oh btw I noticed that you posted this in 2010 so you probably won’t even see this.
