My physics class is intro more or less (it's calc based; 111 NOT 101). I'm a bit confused when it comes to springs..specifically, finding the maximum compression a spring will have.
Here are the given variables in a problem in my textbook:
*spring has negligible mass
*force constant(k) = 1600n/m
*spring is placed virtically with one end on the floor
*1.2kg book is dropped from a height of .80m above the top of the spring
maximum distance the spring will be compressed?
what confuses me specifically are the signs (+/-) and the distances involved. Here is what I am thinking:
I need to use K1 + U1 = K2 + U2 (k1 = zero)
now when it comes to potential energy, i don't know whether to use MGY or 1/2kx^2..can someone point me in the right direction? thanks!
