Can the velocity of an object be in a direction other than the direction of acceleration?

Is it possible that the velocity of an object be in a direction other than the direction of acceleration?

What is the direction of acceleration?

Can be the direction cosines of a line?

State which of the following situations are possible and give an example for each of these.an object moving in a certain direction with an acceleration in the perpendicular direction.

Drift velocity in a metallic conductor: At room temperature there are large number of free electrons having zero average velocity, but when electric field is applied, the free electrons start moving in a direction opposite to the direction of the applied field with a velocity called drift velocity. Magnitude of acceleration produced in each electron by the electric field is

Average thermal velocity of the electron is

A proton having charge e enters a magnetic field of strength B with a velocity v in a direction making angle theta with the direction of the field. The force on proton is
