A rifle bullet with mass 8.00 g strikes and embeds itself in ablock with mass 0.912 kg that rests on africtionless, horizontal surface and is attached to a coil spring.The impact compresses the spring 15.0 cm. Calibration of the springshows that a force of 0.750 N is required to compress the spring0.250 cm.
a) Find the magnitude of the block's velocity just after impact.
b) What was the initial speed of the bullet?
