A electron moving along the x-axis has a position given by x = 18 te-2.5 t m, where t is in seconds. How far is the electron from the origin when it momentarily stops? I am pretty sure that I have to differentiate this equation, and find where it equals zero and solve, I guess the biggest...

Yea I am knd of stuck on it I believe you have to find the magnitude by using the pythagorean theorem but calculating the angle is what is giving me trouble

In the sum A + B = C, vector A has a magnitude of 10.1 m and is angled 46.0° counterclockwise from the +x direction, and vector C has a magnitude of 16.8 m and is angled 17.7° counterclockwise from the -x direction. What are (a) the magnitude and (b) the angle (relative to +x) of B? State your...

what do you mean by in terms of in terms of thickness and area

Gold, which has a mass of 19.32 g for each cubic centimeter of volume, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber. (a) If a sample of gold with a mass of 7.000 oz, is pressed into a leaf of 7.000 μm thickness, what is the area (in m^2) of the...
