a 263 g block is dropped onto a vertical spring with force constant k = 2.52N/cm. the block sticks to the spring and the spring compresses 11.8cm before coming momentarily to rest. while the spring is being compressed how much work is done (a)by the force of gravity (b) by the spring (c)what was the speed of the block before it hit the spring

k=250N/m.
Also, m=0.263kg.
Then, x=0.11m.
h=0.57m[mgh=0.5×kx²]
Also, 1.50J =potential energy.
energy due to the spring can be calculated.
use,u=0,h=0.57m,and a=10m/s².
use ,v²-u²=2ah. to evaluate (c)
