I'm sorry I'm new here. How do i approve your pending graph?

I did inverse tangent of sum of y's over the sum of x's. Thus: tangent-1 (2.125/11.24) = 10.70 .. am i doing this right?

oh wait! i posted before i saw your responds. I'll take a look again at my numbers.

I sketched a right triangle, and I for the height i added up the y-components and for the x i added up all the x-components. the hypot i put the magnitude. So to find the angle, does it mean i can use either cos, sin, and tangent?

First of all thank you Redbelly98, Leong, and Sheneron for all your help. It's very much appreciated. I got the right answer which came out to be 0.914 =D now on to the 2nd part: 2. Find the direction of its average velocity between these two points. ( degree is counterwise from +x axis. )...

I subtracted x2-x1 and added it with y2-y1 and took the square root my magnitude came out to be 1.0703 but it was wrong

Homework Statement A meteor streaking through the night sky is located with radar. At point A its coordinates are (5.20km, 1.20km), and 1.18 s later its has moved to point B with coordinates (6.24, 0.915). 1. Find the magnitude of its average velocity between these two points. 2. Find...

Thank you for replying so quickly! I love this site already .. hehe Anyhow! I think I understand what you are saying. Basically, The coefficient of friction of the block stays the same, but as the block is tilted sideways, gravity will continue to pull the block down which changes the normal...

Homework Statement Imagine a block sitting on an inclined plane rather than a flat surface. The angle Ө made by the plane relative to the horizontal can be changed. We could determine the coefficient of kinetic friction by inclining the plane (increasing Ө) until the block slides at a constant...
