That is roughly what I get so we'll allow for errors in roundings. Do you understand how you got the answer though? There is no point explaining the next bit if this hasn't made any sense.

Cool, glad to here it.

(b) Determine the angle of the velocity vector of the package just before impact.
How do you think we approach this bit then? What information do we know relating to the package just before it hits the ground?

its velocity is 59.6m/s
the x component is 59.6cos40
the y component is 59.6sin40

The x component is right as we know it is constant but the y component changes with time because of the acceleration due to gravity.

Yer, I got 68.3 so allowing so inaccuracy with rounding it is all cool.
