A rifle bullet with mass 8.00 gg strikes and embeds itself in a block with mass 0.992 kgkg that rests on a frictionless, horizontal surface and is attached to an ideal spring. The impact compresses the spring 15.0 cm. Calibration of the spring shows that a force of 0.750 N is required to compress the spring 0.250 cm 1)  Find the magnitude of the block's velocity just after impact.
