A body projected horizontally moves downward with increasing vertical speed true or false​

I don't think so

False is the answer may be

We have that for the Question "Dona rolls a marble with a speed of 5.0/m/s across a level table that is 1.6m above the floor" it can be said that the travel in the x direction is

x'=2.85m

From the question we are told

Dona rolls a marble with a speed of 5.0/m/s across a level table that is 1.6m above the floor. Upon reaching the edge of the table it follows a parabolic path to the floor . How far does the marble travel in the x direction

Generally the equation for the kinematic equation  is mathematically given as

t=0.57s

Therefore

The Horizontal distance

x'=2.85m

For the QUestion"How far does the marble travel in the x direction"

x'=2.85m
