Answer: 9kgm/s

Explanation:

Given that,

Mass of ball = 3 kg

Speed by which ball moves = 3 m/s. Linear momentum of the ball = ?

Since momentum refers to the quantity of motion of the moving ball,

Linear momentum = Mass x Speed

= 3kg x 3m/s

= 9 kgm/s

Thus, the linear momentum of the ball is 9kgm/s
