A ball is thrown from position L and caught at position N.
L and N are the same height above the ground.
If vectors directed upwards are taken as positive, and air resistance is neglected, then the acceleration of the ball at L is -g and its speed is v.
Select the row of the table that correctly gives the acceleration and the speed of the ball as it reaches N.
