Question

(a)What is momentum? Give its S.I unit. Derive Newton's Il law of motion mathematically
(b)A body of mass 60 kg has a momentum of 300 kg m/sec. Calculate its velocity?​

Answer 1

Explanation:

1. In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s. Newton's second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes
