Atennis player throws a ball vertically upwards at 4.90 m/s. how long, in seconds, does the ball take to return to his hand (assuming it has not moved since releasing the ball)? assume a gravitational acceleration of g = 9.8 m/s^2 and give your answer to 2 decimal places.

If ball return to the hand of player then we can say that displacement of ball will be zero

so here we will have

so here we will have
