Terminal velocity is when the object falls at a constant velocity... Can you infer at what time it begins falling at constant velocity ?The ball is accelerating as long as the graph has a positive gradient, though, the magnitude of the acceleration reduces with time.Area under the graph whilst at constant velocity (see first point).Area under the WHOLE graph.
a(i) i wrote 4.5/5/6 but answer was different so i didnot knoww why???
It has to be a range.
