(From Kaplan) A bloc of mass "m" starts from rest and slides down a frictionless semi-circular track from a height "h". When it reaches the lowest point of the track, it collides with a stationary piece of putty also having mass "m". If the block and the putty stick together and continue to slide, the maximum height that the block-putty system could reach is:
a) h/4
b) h/2
c) h
d) independent of h
The answer is h/4. And the solution goes through a super long substitution (that I don't really get), re-arrangement of kinetic energy and momentum formulas..I was wondering if there is an easier way to do this problem (faster too). Thanks
