Correct Answer: 6000 units

Solution : The correct option is 6000 units.

The momentum (p) of an object is given by the product of its mass (m) and velocity (v). Mathematically, it is expressed as:

p=m⋅v

If the velocity (v) of the ball is doubled, the new velocity (v _new ​) becomes 2v. The new momentum (p _new​ ) can be calculated using the formula:

p _new ​= m⋅v _new​

Substituting v _new ​= 2v into the equation:

p _new​ = m⋅2v

if the initial momentum (p) is given as 3000 units, the new momentum (p _new ​) can be expressed as:

p _new ​=2⋅p

Substituting p=3000,  p _new​ =2⋅3000

p _new ​=6000

Therefore, if the velocity of the ball is doubled, the new momentum will be 6000 units.
