kg.m/sec
kg.m/sec3
kg.m/sec2
kg.m2/sec
Answer is Right!
Answer is Wrong!
The correct answer is A. kg.m/sec.
Impulse is a vector quantity that describes the change in momentum of an object. It is calculated by multiplying the mass of an object by its change in velocity. The unit of impulse is therefore the same as the unit of momentum, which is kg.m/sec.
Option B is incorrect because it has an extra power of 3 on the mass. Option C is incorrect because it has an extra power of 2 on the velocity. Option D is incorrect because it has units of area, not of momentum.
