Ap Calc exam tomorrow, and I really need to know how to do this...

It is given that an object is moving along a curve in an xy-plane at position (x(t), y(t)), where dx/dt = arcsin(1-2(e^-t)) and dy/dt = (4t)/(1+(t^3)).

At t=2, the object is at (6,3).

The problem asks to find the acceleration vector and speed of object at t=2.
