Explanation:

please mark it as brain liest

Answer 2

★ Question Given :

• ⇢Mass of Bullet (m) = 30g [ 0.03 kg ]
• ⇢Mass of Gun (M) = 7 kg
• ⇢Velocity of Bullet (V) = 400m/s

★ Need to Calculate :

• ➟ Recoil velocity of the gun ?

★ Formula Used Here :

• ➻ ☆ V = mv / M ☆

______________________

✠ Where :

• ↠ V = Velocity
• ↠ m = Mass of bullet
• ↠ M = Mass of gun

⚘ Putting Value in Formula :

• ➬ V = mv / M
• ➬ V = ( 0.03 × 400 ) / 7 m/s
• ➬ V = 12 / 7 m/s
• ➬ V = 1.71m/s

⌬ Therefore :

» ❝ Recoil velocity of gun will be 1.71 m/s. ❞
