Question

Calculate the momentum of a bullet of 20 g when it is fired from a gun with a velocity of 100 m/s; Calculate the momentum of a bullet of 20 g when it is fired from a gun with a velocity of 100 m/s

Answer 1

We have,

m = 20 g = 0.020kg

v = 100 m / s

So, momentum = mv

= 0.020 x 100

= 2.000 kg m / s.

Answer 2

ʜᴇʏ ᴍᴀᴛᴇ!

sɪɴᴄᴇ, ᴍᴀss = 20ɢ = 0.020ᴋɢ

ᴀɴᴅ ᴠᴇʟᴏᴄɪᴛʏ = 100 ᴍ/s.

ᴡᴇ ᴋɴᴏᴡ ᴛʜᴀᴛ, ᴍᴏᴍᴇɴᴛᴜᴍ = ᴍ × ᴠ = 0.020 × 100 = ２ ᴋɢ.
