I need help with these two questions about physics, pls help if you can ! ty! I give lots of points and wrong answers will get reported
1. A 0.008 kg bullet is fired horizontally into a 9.00 kg cube of wood, which is at rest, and sticks in it. The cube is free to move and has a speed of 0.04 m/s after impact. Find the initial velocity of the bullet.
2.A 0.090 kg ball moving at 1 m/s collides with a stationary 0.010 kg ball. Determine the speed of the 0.90 kg ball if the 0.10 kg ball has a velocity of 1.8 m/s after impact if the collision is perfectly elastic.
