Question

calculate the velocity of a missile having mass of 100kg. If it attains a momentum of 5000kg m/s when fired from a rocket gun​

Answer 1

ɢɪᴠᴇɴ :-

• Mass(m) = 100kg
• Momentum(p) = 5000 kg. m/s

Tᴏ ғɪɴᴅ :-

• Velocity(v) of missile

sᴏʟᴜᴛɪᴏɴ :-

We know that,

➦ Momentum(p) = Mass(m) × Velocity(v)

➦ p = m × v

Put the above given values in it, we get,

➮ 5000 = 100 × v

➮ 5000/100 = v

➮ v = 50 m/s

Hence,

• Velocity of Missile is 50 m/s
