A body is thrown vertically upwards which graph represents variation of velocity w.r.t time

A body is thrown vertically upwards and rises to a height of 10m. The velocity with which the body was thrown is (g - 9.8m/( s^(2) )

A ball is thrown vertically upwards. Which of the following graph/graphs represent velocity time graph of the ball during its flight ( air resistance is neglected).

A ball is thrown vertically upwards. Which of the following graph/graphs represent velocity-time graph of the ball during its flight (air resistance is neglected)

A ball is thrown vertically upwards. Which of the following graph/graphs represent velocity-time graph of the ball during its flight (air resistance is neglected)

At time t=0 a body is thrown vertically upwards with a velocity "50m/sec" .At time t=2 sec another body is thrown vertically upwards with the same velocity "50m/sec" .the two bodies will meet at time__ sec (a=10m/sec^(2))

A body A is thrown vertically upwards with such a velocity that it reaches a maximum height of h. Simultaneously, another body B is dropped from height h. It strikes the ground and does not rebound. The velocity of A relative to B versus time graph is best represented by (upward direction is positive).
