Question

two objects of mass 0.1kg and 0.2kg are moving along the same line and direction with a velocity of 2m/s and 1m/s respectively. calculate the total momentum.

Answer 1

Given:

m₁ = 0.1 Kg

m₂ = 0.2 Kg

v₁ = 2$\frac{m}{s}$

v₂ =1$\frac{m}{s}$

To find:

The total momentum

Solution:

ρ = m₁v₁ + m₂v₂

ρ = (0.1 × 2) + (0.2 × 1)

ρ = 0.2 + 0.2

ρ = 0.4 kg.$\frac{m}{s}$
