A 360.0 $g$ block is dropped onto a vertical spring with a spring constant k = 254.0 $N/m$. The block becomes attached to the spring, and the spring compresses 0.26 $m$ before momentarily stopping. While the spring is being compressed, what work is done by the block's weight?

Respuesta :

Answer:

8.6 J

Explanation:

Work done by the block = change in energy in the spring

W = ½ kx²

W = ½ (254.0 N/m) (0.26 m)²

W = 8.6 J
