If a ball is thrown vertically upwards at initial time 0. Draw the velocity graph with respect to time (v - t graph) for the ball’s motion, from the initial time 0 to the moment that the ball reaches the ground. (Assume free fall motion).

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud
