An 80-G Bullet Is Suddenly Shot into a 4 $10 \mathrm {~N} \cdot \mathrm { s }$

question 92

Multiple Choice

An 8.0-g bullet is suddenly shot into a 4.0-kg block, at rest on a frictionless horizontal surface, as shown in the figure. The bullet remains lodged in the block. The block then moves against a spring
And compresses it by 8.9 cm. The force constant (spring constant) of the spring is 1400 N/m. What
Is the magnitude of the impulse on the block (including the bullet inside) due to the spring during
The entire time interval during which the block compresses the spring?

• A) \(10 \mathrm {~N} \cdot \mathrm { s }\)
• B) \(13 \mathrm {~N} \cdot \mathrm { s }\)
• C) \(8.3 \mathrm {~N} \cdot \mathrm { s }\)
• D) \(12 \mathrm {~N} \cdot \mathrm { s }\)
• E) \(6.7 \mathrm {~N} \cdot \mathrm { s }\)
