Answer: The two vehicles moved in the direction of the truck after collision

Explanation: Given that

Mass of the car M1 = 800 kg

Mass of the truck M2 = 1600 kg

Since the two vehicles move together after collision, then, the collision is inelastic. Therefore

M1U1 - M2U2 = (M1 + M2) V

U1 = U2 = 15 m/s

(800 * 15) - (1600 * 15) = (800 + 1600) V

12000 - 24000 = 2400V

2400V = - 12000

V = - 12000/2400

V = - 5 m/s

Since V is negative, and M2U2 is also negative, therefore,

The two vehicles moved in the direction of the truck after collision
