🤓 Based on our data, we think this question is relevant for Professor Cook's class at ODU.

Solution: A 13.9 g bullet is fired horizontally into a 0.518 kg wooden block resting on a horizontal surface (μ = 0.125). The bullet goes through the block and comes out with a speed of 233 m/s. If the block travels 7.29 m before coming to rest, what was the initial speed of the bullet? The acceleration of gravity is 9.8 m/s2. 1. 421.185 2. 462.083 3. 475.131 4. 428.393 5. 771.008 6. 608.548 7. 390.493 8. 415.722 9. 506.991 10. 636.296
