what is the volume of a rectangle prism with a length of 5.6cm, a width of 2.1cm and a height of 6.6cm?

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
