\mathbf{A}

Q3PhysicsUnit 3: Laws of Motion

A machine gun fires 10 bullets/s, each of mass

10 g

, the speed of each bullet is

20 c m / s,

then force of recoil is

Q4PhysicsUnit 3: Laws of Motion

A particle of mass

m

moving with a velocity

(3 \hat{i}+2 \hat{j}) m s^{-1}

collides with another body of mass

M

and finally moves with velocity

(-2 \hat{i}+\hat{j}) m s^{-1} .

Then during the collision: This question has multiple correct options

Q5PhysicsUnit 3: Laws of Motion
