Find the instantaneous velocity where r is the position vector as a function of time:
r(t)=(3.0m/s^2)t[itex]\hat{x}[/itex]+(4.0m/s)t[itex]\hat{y}[/itex]
I attempted to find the derivative of this to find instantaneous velocity, but the book's solution was different. I think the author of the book may have made a mistake, but if not, I would like to know what I've done wrong.
My answer: v(t)=(6.0m/s)t[itex]\hat{x}[/itex]+(4.0m/s)[itex]\hat{y}[/itex]
Book's answer: v(t)=(6.0m/s^2)t[itex]\hat{x}[/itex]+(4.0m/s)[itex]\hat{y}[/itex]
r(t)=(3.0m/s^2)t[itex]\hat{x}[/itex]+(4.0m/s)t[itex]\hat{y}[/itex]
