there is an acceleration vector. What will be the velocity vector for that motion for time t?

if [itex]\underline{a}[/itex] = 4t[itex]\underline{i}[/itex] + t[itex]^{2}[/itex][itex]\underline{j}[/itex]

then [itex]\underline{v}[/itex] = 2t[itex]^{2}[/itex][itex]\underline{i}[/itex]+ [itex]\frac{t^{3}}{3}[/itex][itex]\underline{j}[/itex] + some constant vector.

but [itex]\underline{F}[/itex] = m[itex]\underline{a}[/itex]

therefore

[itex]\underline{v}[/itex] = [itex]\int[/itex][itex]\frac{\underline{F}}{m}[/itex]dt
