Homework Statement
For each of the following cases, represent on the trajectory, the velocity and tangential and normal components of the acceleration at times t1 and t2 of a mobile that moves according to the graph of s (arc) versus t (time) on the left. The point O on the trajectory marks the origin
of arcs and the arrow indicates the direction of the rising arc. Indicate also when it is greater
the speed of the mobile, in t1 or t2.
Homework Equations
v= dS/dt
The Attempt at a Solution
I have tried it. But I don't understand what means when the graphic is drawn in the negative area.
I think there is many mistakes in my attempt.
