Question

A sphere of mass 2kg strikes another sphere of mass 3kg at rest with a velocity of 5ms-1 if they move together after Collision, then common velocity is

Answer 1

Answer:

common velocity is 2 m/s

Explanation:

$Mass(M_{1}) = 2 kg\\\\Mass (M_{2}) = 3 kg$

$Velocity of Mass 2 kg (V_{1} ) = 5 m/s$

$By Law of conservation of linear momentum\\\\M_{1}V_{1} = (M_{1}+ M_{2} )V$

$V is common velocity after collision$

10 = 5*V

V = 2 m/s
