1. The problem statement, all variables and given/known data

A 2.0 kg block is dropped from a height of 40 cm onto a spring of force constant k = 1960 N/m. The maximum distance the spring is compressed is?

2. Relevant equations

I Used the equation W=mgh and W=1/2kx^2..

3. The attempt at a solution

i did..

W=2*9.8*0.4

=7.84

then i used

7.84=1/2*1960*x^2

from which i gotx=0.0894427191

then i did

7.84*0.0894427191=0.7012309177

then i did

7.84-0.7012309177=7.13879

can anyone plz help me tel where i went wrong? because the answer to this question is 10 but i dont know how to get it..plz help=].
