1. The problem statement, all variables and given/known data In the xy plane, where distances are measured in feet, a 96 lb object is moving from left to right on the curve y=e^-x. At t-0 its speed is 6ft/s and is speeding up at (square root of 8) ft/s^2. what is the total force on it at that point? Give floating point values for the magnitude and angle of inclination of this force. 2. Relevant equations F=ma 3. The attempt at a solution I just don't really know where to begin. i'm sure once i get started on the right track, i can finish it. we know that the point in question is (0,1), and we know v(0)=6 ft/s and a(0)=sqrt8 ft/s^s. and we know y=e^-x, dy/dx= -e^-x, and second derivative= e^-x. the unit tangent is i-j and the unit normal is i+j. Now i'm stuck. do i need to use the breakdown of a into componets equation with the curvature and whatnot?
