Question

Two bodies of masses 2 Kg and 7 Kg are moving with velocities of 2 m/s and 7 m/s respectively. What is the total momentum of the system in Kg-m/s? *

Answer 1

$\bf\huge\underline{\underline{ Given :- }}$

• $\bf m_{1} = 2Kg$

• $\bf m_{2} = 7Kg$

• $\bf v_{1} = 2m/s$

• $\bf v_{2} = 7 m/s$

$\bf\huge\underline{\underline{ To \: Find:- }}$

• Total momentum

$\bf\huge\underline{\underline{ Answer :- }}$

• $p_{1} = m_{1}v_{1}$

• $\red{\implies}$ 2 × 2

• $\red{\implies}$ 4Kg m/s

$\rule{10cm}{0.05cm}$

• $p_{2} = m_{2}v_{2}$

• $\red{\implies}$ 7 × 7

• $\red{\implies}$ 49 kg m/s

$\rule{10cm}{0.05cm}$

• Total momentum = $p_{1} + p_{2}$

• $\red{\implies}$ 4 + 49

• $\red{\implies}$ 53 kg m/s
