An object of mass m is at rest in equilibrium at the origin. At t=0 a new force F⃗ (t) is applied that has components
Fx(t)=k1+k2y,Fy(t)=k3t,
where k1, k2, and k3 are constants.

Part A

Calculate the position r⃗ (t) vector as function of time.

Part B

Calculate the velocity v⃗ (t) vector as function of time.

I know that you have to derive to figure out these equations im just not sure where to start, help would be much appreciated :)
