Displacement vectors of 3m and 5m in the same direction combine to make a displacement vector that is?
2 m
How are speed velocity and acceleration different?
Velocity is a vector, meaning that it has a direction. When it is being expressed, the direction is given with it (e.g. 5m/s NW). Speed is a scalar, not a vector, so it doesn't have a direction connected with it. Thus, when it is expressed, the direction variable is omitted (e.g. 5m/s). Acceleration is a change in velocity or speed over time. It will be a vector when it is referring to a change in velocty (e.g. 10m/s2 SE), and it will be a scaler when it is referring to a change in speed (e.g. 10m/s2).

It is a displacement vector.
Displacement vectors of 3m and 5m in the same direction combine to make a displacement vector that is?
2 m
Does a unit vector have direction?
No it doesn't. A unit vector indicates direction only. The length of the orthogonal components are RELATIVE to the absolute length of the vector, thus cannot have a unit. For instance, let X'=X/x where X is a vector, x is a scalar and X' is a unit vector. X has length and direction and x has length only, thus X' has direction only. Here's an example. C = A + B where A=3m*A' and B=4m*B' (where A and B are orthogonal) cC' = aA' + bB' C' = (a/c)A' + (b/c)B' = xA' + yB' c = sqrt(3m^2+4m^2) = 5m (by pythagorous) x = (3m/5m) = (3/5) (notice that the units cancel out!) y = (4m/5m) = (4/5) (notice that the units cancel out!)
