Answer ⇒ Vx = + 4.33 m/s.

Option (b).

Explanation ⇒

Refer to the attachment for the question.

    v = 5m/s.

Vx = VSin60

Vx = 5 × √3/2

∴ Vx = + 4.33 m/s.

Hence, the component of the velocity that we can easily figure out from the figure is + 4.33 m/s.

Hence, Option (b). is the correct choice.

Hope it helps.

answer

0.004 kg m/s

explanation:

given : mass= 200g = 0.2 kg

velocity = 2cm/s = 0.02 m/s

momentum= mass x velocity

= 0.2 kg x 0.02 m/s

= 0.002 kg m/schanges in mass

an object's mass and momentum are directly related; as mass increases, momentum will have a corresponding increase, assuming a constant velocity. thus, an object with twice the mass of another object -- moving at the same speed and in the same direction -- will have twice the momentum.
