Thank you all for the help, thank you Ray Vickson and the mentors as well. So Mr. Vickson, I found the answer to be 0 via calculations but I only vaguely understand why it is 0. Is it because whenever you take dot product, which is a scalar of how much one vector lies along another vector, and...

The image of the graph is attached below:

Homework Statement A golf ball is struck at ground level. The speed of the golf ball as a function of the time is shown in the figure, where t = 0 at the instant the ball is struck. The scaling on the vertical axis is set by va= 16 m/s and vb= 29.3 m/s. (a) How far does the golf ball travel...

oh, ok, so the direction is actually -63.098 degrees because tan ^-1 (-814.2/413).

Wait, is (a) correct, then why did you say that I should change the sign of the displacement?

Is the answer to d and b the same?

Homework Statement A plane flies 413 km east from city A to city B in 49.0 min and then 814 km south from city B to city C in 1.70 h. For the total trip, what are the (a) magnitude and (b) direction of the plane's displacement, the (c) magnitude and (d) direction of its average velocity, and...

I'm sorry can you please tell me at least the next step, i am confused and have been at this for hours.

Is it in degrees? I am just confused I see the picture, its like perpendicular.

so how do i find orientation though?

I try plugging it into a times b sin theta = magnitude of cross product but it just doesn't work.

I don't know it doesn't work.

so isn't it just: ok so we have 10.05 times 26.83 times sin of theta=309.22. So then theta=309.22/269.6*(arcsin)

Isn't cross product equal to magnitude of a times magnitude of b times sin of theta?

so isn't the cross product equal to magnitude of a times magnitude of b multiplied by sin of theta?
