Question

an object of mass 2 kg travelling along a
Straight line with a velocity of 8m/s.find
its momentum)a)16 kg ms.
b)4 kg m/s
c)4 kg ms (d)16 kg m/s​

Answer 1

$m = 2 \: kg$

$v = 8 \: ms {}^{ - 1}$

$momentum = mv$

$= 2kg \times 8 \frac{m}{s}$

$=16kg.ms^-1$

$\huge\pink{\boxed{= 16 \: \frac{kgm}{s}}}$

$\large\red{\mathbb{OPTION \: a)\: IS\: CORRECT}}$

Answer 2

Answer :

➥ The momentum of an object = 16 kg m/s

Given :

➤ Mass of an object (m) = 2 kg

➤ Velocity of an object (v) = 8 m/s

To Find :

➤ Momentum of an object (p) = ?

Solution :

As we know that

$\tt{:\implies p = mv}$

$\tt{:\implies p = 2 \times 8}$

$\bf{:\implies \underline{ \: \: \underline{ \purple{ \: \: p = 16 \: kg \: m/s \: \: }} \: \: }}$

Hence, the momentum of an object is 16 kg m/s.
