Solve the all parts of given question:
Question: A riffle bullet with mass 8 g strikes and embeds itself in a block with mass .992 kg that rests on a frictionless horizontal surface and is attached to a coil spring. That impact compresses the spring 15 cm. Calibration of the spring shows that a force 0f .750 N is required to compress the spring .25 cm.
Part I: Find the magnitude of the blocks velocity just after impact?
Part II: What is the initial speed of the bullet?
I need help to determine the magnitude of the blocks velocity just after impact.
