As per your syllabus, how many conservation equations does linear momentum yield in 3D?
AZero (no conservation)
BOne equation per body
CThree (one per axis)
DTwo equations of motion
Answer & Solution
Correct answer: C. Three (one per axis)
Your syllabus: p is a vector
conservation gives 3 component equations (Δp_x = Δp_y = Δp_z = 0).
