The graph given below represents motion of what? And what type of motion is it? Assume that the downward direction in the graph is negative. Also find the value of t. Assume no loss of energy anywhere. Assume disp =0 implies ground level.

• A. Ball thrown up with velocity u, periodic motion, t = u/g
• B. Ball left from a height h, periodic motion, t = √(2h/g)
• C. Ball thrown up with velocity u, oscillatory motion, t=u/g
• D. Ball thrown up with velocity u, periodic motion, t=2u/g
