Explanation:
Linear momentum is the product of mass and velocity...It is vector quantity and direction of it is along direction of velocity..
➡ Linear momentum,,L = m × v
Where,,m is mass of the body and v is velocity of that body...
➡ So,,unit of linear momentum is kgm/s and ,,,dimension is [ MLT-¹ ]
✳ Impulse:- It is a physical quantity having same,,unit and dimension of linear momentum..
As impulse is large force imparted in short interval of time ...
➡ e. g. impulse = F. ∆t
✳ Unit of force is kgm/s² and unit of time change in sec..
➡ So,,unit of impulse is kgm/s ...
➡ It is same as unit of linear momentum..
✳ Similarly,,dimension of impulse is also,,,,,,[MLT-¹]
Hope it will be helpful ✌✌✌
