Perfectly Inelastic Collision:

Perfectly elastic head on collision

According to law of conservation of momentum

m1u1 + m2u2 = m1v1 + m2v2m1 (u2–v1) = m2 (v2–u2)

According to law of conservation of kinetic energy

1/2 m1 u21 + 1/2 m2 u21 = 1/2 m1 v21 + 1/2 m2 v22m1 (u21–v21) = m2 (v22–u22)u1 – u2 = u2 – v1

(i)  If projectile and target are of same mass i.e. m1 = m2

(ii) If massive projectile collides with a light target i.e. m1 >> m2

(iii) If light projectile collides with a very heavy target i.e. m1 >> m2
