A ball is thrown vertically upwards with a certain velocity. Then

A ball is thrown vertically upwards with an initial velocity of 49 m s^(-1) . Calculate the time taken by it before it reaches the groung again (Take g= 9.8 m s^(-2) )

A ball is thrown vertically upwards with a velocity of 49 m/s. Calculate the total time it takes to return to the surface of the earth.

A ball is thrown vertically upwards with a velocity of 49 ms^-1 . Calculate :The total time it takes to return to the surface of earth.
