An object of mass m has a kinetic energy E . Another object has a mass m and kinetic energy E . The objects have the same momentum. What is the ratio

true

explanation:

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

it is a negative acceleration
