In this item, it is assumed that what is being asked is the final velocity and direction after collision. This can be answered through the conservation of momentum.

Momentum is the product of the mass and the velocity,

M = m x v

If we take east as positive then, west would be negative.

Through the conservation,

(1050) (-15 m/s) + (6320 kg) (14 m/s) = (1050 + 6320) x v

The value of v from the equation is 9.87 m/s. Since it is positive, the direction is east.
