| Statement 1: A body thrown vertically up with a velocity u reaches the maximum height h after T seconds. At a time 2T seconds its velocity becomes zero. |
| Statement 2: A particle thrown vertically up with a velocity comes back to its initial position with same magnitude of velocity but in opposite direction. |
A) Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B) Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C) Statement 1 is true but statement 2 is false.
D) Statement 1 is false but statement 2 is true.
Correct Answer: D
Solution :
During upward motion, initial velocity is \[\overline{u}\]and maximum height is h after time T seconds. \[\therefore \] Velocity at maximum height = 0 During downward motion, initial velocity is zero. height covered is h after T seconds. \[\therefore \] Final velocity \[=-\overline{u}\] So it can be concluded that at a time 2T seconds its velocity becomes\[-\overline{u}\].
