Question

a) Define momentum. State its SI unit.
b) An object of mass 50Kg is accelerated uniformly from a velocity of 4n/sto Smis in s
Calculate the initial and final momentum of the object. Also find the magnitude of the force
exerted on the object. ​

Answer 1

Explanation:

the product of mass ond velocity is called momentum kgm) s

Answer 2

Momentum :----> it is defined as the product of mass and velocity .

it is denoted by latter "p"

Mathmatical form

P =mv

where

m= mass of body .

v = velocity of body

Momentum follow the law of conservation law

Si unit = kgm/s

Given

M = 50kg

v =4m/s

u =0

pi= mu = 0

pf = mv = 50*4 = 200kgm/s
