Agent Arlene devised the following method of measuring the muzzle velocity of a rifle. She fires a bullet into a 4.350-kg wooden block resting on a smooth surface, and attached to a spring of spring constant k = 140.0 N/m. The bullet, whose mass is 7.750 g, remains embedded in the wooden block. She measures the maximum distance that the block compresses the spring to be 9.460 cm.(Figure 1) Figure m M 9.460 9.460 cm-- M+m 1 of 1 Part A What is the speed of the bullet?

Agent Arlene devised the following method of
measuring the muzzle velocity of a rifle. She fires a
bullet into a 4.350-kg wooden block resting on a
smooth surface, and attached to a spring of spring
constant k = 140.0 N/m . The bullet, whose mass is
7.750 g, remains embedded in the wooden block. She
measures the maximum distance that the block
compresses the spring to be 9.460 cm.(Figure 1)
