An object is projected horizontally with an initial velocity of 3.0m/s

A) When will the vertical displacement be 5.0m
B) What will the horizontal displacement be at this time

Have difficulty's with A

Consider vertical components and then use the equations of motion.
 
You can use the kinematic equations in the vertical direction, once you know the value of the downward acceleration in the vertical y direction and the initial velocity in the y direction. Identify these values as 'givens', then which of the kinematic equations would you choose?
 
thanks
i was getting really close but not quite but i just realized that there is only one sig fig,
so when i round it i get the right answer
