If the particle’s position on the xaxis is now given by the function x=(1t^2+1t+2)m, where t is in s. To the nearest 0.1 m, what is the turning point (where the particle reverses direction of motion) of the particle's position?

Best ResponseYou've already chosen the best response.3the function is:\[x(t)=t ^{2}+t2\] right?

Best ResponseYou've already chosen the best response.0So sorry the actual function is x=(2t^2+0t+5) not the one stated above.

Best ResponseYou've already chosen the best response.3the turning point is a point at which the derivative changes sign

Best ResponseYou've already chosen the best response.3so you should derivate the function and see when the derivative becomes zero. And when you find that turning point then you will have to evaluate in your position function to know at what position was the particle when it reverse his direction of motion.
