Ok all you engineers and smart people I have a question that I just can’t seem to get right. So if you would please help me out:
An electron moving along the x axis has a position given by x = 13 te^-2.5t m, where t is in seconds. How far is the electron from the origin when it momentarily stops?
Pretty much I’ve figured out that the velocity is the derivative of that function and when the electron stops its velocity is zero. So figure out the derivative and set it equal to zero and solve for t. There is a chain rule and a product rule I believe but its not working out. My calculus is pretty rusty and i’ve got one more attempt at this online question. Thanks in advance!
