(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a .46kg block is attached to a horizontal spring that is at equilibrium length, and whose force constant is 22 N/m. The block rests on a frictionless surface. A 5.2x10-2 wad of putty is thrown horizontally at the block, hitting it with a speed of 2 m/s and sticking.

How far does the putty-block system compress the spring

2. Relevant equations

E1=E2

3. The attempt at a solution

K1U1=K2U2

1/2 (m1+m2) v^2=1/2Kx^2

1/2 (.052+.460)(.203^2)=1/2(22)x^2

i got x=.042 but it is saying this is incorrect
