if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
