It depends on the force that is applied to the object.
How long it takes to earth to revolve completely on its Axis
You would want to include qualitative and quantitative evidence
Objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities.
We know that the centripetal acceleration is zero, since the summation of forces is the mass times the acceleration in the x- component.
