Question

A bullet of mass 30g is Fired from on of gun 7 kg oF the velocity of bullet is 400m/s then the recoil velocity of the gun will be​

Answer 1

⠀⠀⠀⠀⠀⠀⠀⠀⠀Gɪᴠᴇɴ : ⇩

• Mass of bullet (m) = 30g [ 0.03 kg ]

• Mass of gub (M) = 7kg

• Velocity of bullet (V) = 400m/s

⠀⠀⠀⠀⠀⠀⠀⠀Tᴏ Fɪɴᴅ : ⇩

• Recoil velocity of the gun ?

⠀⠀⠀⠀Fᴏʀᴍᴜʟᴀ ᴜsᴇᴅ ʜᴇʀᴇ : ⇩

• V = mv/M

⠀⠀⠀⠀⠀⠀⠀⠀Wʜᴇʀᴇ : ⇩

• V = Velocity

• M = Mass of bullet

• M = Mass of gun

Pᴜᴛᴛɪɴɢ ᴠᴀʟᴜᴇs ɪɴ ғᴏʀᴍᴜʟᴀ : ⇩

• V = mv/M

• V = ( 0.03 × 400 )/7m/s

• V = 12/7m/s

• V = 1.7m/s
