Bloody Hell, I've done 2 years of physics but I'm just doing something wrong with problem yet it's so basic.
Any ideas on what I'm doing wrong??

Ah it's too late now the home work was due at 11:59
I know Δp=FnetΔt and ΔP=mv
One question i do have is whether force parralel +force perpindicular are considered F net or not I feel like it should be F|| cross Fp

Written as vectors, as in the very first item: Yes, force parallel +force perpendicular = force, probably net force, depending on the contextC R P said:
What is the difference between the following two statements?
[itex]\displaystyle \vec{P}=\vec{F}_{\text{net}}\Delta t[/itex]
[itex]\displaystyle \vec{P}_\text{f}=\vec{P}_\text{i}+\vec{F}_{ \text{net}}\Delta t[/itex]
?[itex]\displaystyle \vec{P}_\text{f}=\vec{P}_\text{i}+\vec{F}_{ \text{net}}\Delta t[/itex]
