I am having a bit of difficulty solving this problem. It says:
A particle has position function . What is its speed at time t?
Well I first took the derivative of the function. Then I took the magnitude to find the length which corresponds to the speed. I got my answer to be
, is this answer correct? If so, how would I further simplify it? If it is incorrect, what am I doing wrong?
Any help and feedback is greatly appreciated, thanks.
