A trolley of mass 1.5kg moving with a velocity of 1.2ms-1 collides inelastically with a second trolley of mass 0.5kg moving in the opposite direction with a velocity of 0.2ms -1 .
(a) What is an inelastic collision?
(b) Determine the velocity of the trolleys after collision.

---

(a) A collision in which objects combine / fuse, losing kinetic energy in the process.

(b) Final momentum = Initial momentum (0.5 + 1.5) V = (1.5 x 1.2) + (0.5 x 0.2)
2.0V = 1.8 + 0.1
2.0V = 0.9
V = 0.95 m/s
