A 2.25-g bullet embeds itself in a 1.50-kg block, which is attached to a spring of force constant 785 N/m. If the maximum compression of the spring is 5.88cm find (a) the initial speed of the bullet and (b) the tie for the bullet-block system to come to rest(adsbygoogle = window.adsbygoogle || []).push({});

I used:

E = K + U = .5(.00225)v^2 + 0

E=Umax = .5(785)(.0588)^2

and then solved for v but it's not right. btw the real answer is 897 m/s
