Please help soon! 2 pics are below!

A. (14 points) You are given the following position vs time graph. x(t) t 1. (7 points) Sketch the corresponding velocity vs time graph (qualitative only). v(t) t2. (7 points) Sketch the corresponding acceleration vs time graph (qualitative only). If you think there is an acceleration, you may assume its constant. alt) t B. (6 points) A particle moving in one dimension has the following position as a function of time: x (t ) = A + Bt2 + Ct3 where A, B and C are constants. Determine the velocity and acceleration of the particle as a function of time
