A round ball with a mass of 90.0 grams compresses a spring (with a constant k = 475.) by 0.25m. When the ball is released, the spring pushes it across a frictionless horizontal surface, until the ball collides with a wooden block of mass 1.50 kg. If the wooden block has a cylindrical cut-out drilled halfway into it that the ball will fit in, so that the ball will slide inside of the block and remain stuck inside, what velocity will the block have after the ball strikes it and sticks?
