Explanation:

I didn't know

Answer 2

Explanation:

• Mass of bullet (m) = 10g = 0.01 Kg
• Initial speed of bullet (u1) = 400 m/s
• Mass of block (M) = 900g = 0.9 Kg
• Initial speed of block (u2) = 0

After collision bullet get struck in the block, so they will have common velocity Vcom

By conservation of Linear Momentum

Initial Momentum = Final Momentum

• M1U1 + M2U2 = M1V1 + M2V2
• m u1 + M u2 = (M1+M2) Vcom
• 0.01 × 400 + 0.9 × 0 = (0.9 + 0.01) Vcom
• 4 = 0.91 Vcom
• Vcom = 4 / 0.91
• Vcom = 4.40 m/s
