Question

A Particle of to kg is moving in a Constant
acceleration 2 m/s² for time 2 sec starting
from the rest. What is its momentum and
velocity

Answer 1

$\huge\underline\color{red}{Answer}$

$\large\color{indigo}{given}$

m= 2kg

acceletion = 2m/²s

time = 2sec

v = o

$\large\color{green}{tofind}$

velocity and momentum

$\large\color{yellow}{explanation}$

to find velocity

we use 1st equation of motion

v = u - at

0 = u - 2×2

u = 4m/s

so velocity is 4 m/s

Now momentum = Mv

P = 2 × 4

P = 8kgm/s

momentum is 8 kgm/s

$\large\color{</strong><strong>orange</strong><strong>}{</strong><strong>extrainfo</strong><strong>}$

momentum:- it's is product of mass and velocity of certain obeject

velocity :- dispalcement coverd in per unit time
