A body of mass 1000 kg is moving horizontally with a velocity $6 \mathrm{~m} / \mathrm{s}$ . If 200 kg extra mass is added, the final velocity (in $\mathrm{m} / \mathrm{s}$ ) is:

Option A:
6
Option B:
2
Option C:
3
Option D:
5
Correct

Answer: D

Step-by-step solution

Momentum will remain conserve

$1000 \times 6=1200 \times v$

$\mathrm{v}=5 \mathrm{~m} / \mathrm{s}$
