An object is launched with an initial velocity of 8 m/s to the horizontal from 327cm above the ground level. The object follows the trajectory path and falls in to the water after 817ms. What is the final speed of the object?

Do you know how to calculate the velocity of an object that is dropped from a height of 3.27m when it hits the ground? Then perform a vector addition of the vertical veklocity and the horizontal velocity as stated in the problem.
