2. (a) Could uniform circular motion be sustained if the force was not perfectly
centripetal, which is to say, that in addition to a purely centripetal component there
was another component to the force that was parallel (i.e. tangential) to the direction of
travel of the satellite? Explain with words and a diagram.
(b) What would happen to the satellite if the direction of the tangential component was
opposite the direction of travel?
(c) What would happen to the satellite if the direction of the tangential component was
the same as the direction of travel?
