Draw velocity time graph for an object thrown upward and reaches to a height h and comes back |
|
Answer» tion:ANSWERFor the first half, when BALL A goes upV A =U A −gTV B =−gTV AB =V A −V B V AB =U.......(1)For the second half, when ball A comes downV A =−gTV B =0V AB =V A −V B V AB =−gT........(2)HENCE from the equation (1) we observe that relative VELOCITY is independent of T. Which will be valid till ball A reaches maximum height point. It is given time taken in reaching h is t.Hence for the time t, V AB will be constant, WHEREAS after time t, relative velocity changes its direction and increases afterwards. |
