A mass being pushed up an inclined plane

[jamiebean]

Homework Statement

attached below

Relevant Equations

gravitational force=mass x 9.8

i tried to solve the problem with the above way

then i calculated Fg= mass x 9.8 = 242.06 N
FgII= Fg x sin50 =185.4287N

so the force required is 185.

is this correct?

It is not correct. Please provide more more details of your solution, specifically the equation you used in symbolic form. You seem to have forgotten the effect of gravity on the block.

What is the "above way"? I don't see it; all I see is a diagram. Are we to assume that the incline is frictionless?
