One Newton is the ___ it takes to change the ___ of a ___ mass by ___ in 1 s

One Newton is the force it takes to change the Velocity of a 1 kilogram mass by 1 meterin 1 s

Explanation:

One Newton is the force it takes to change the velocity of 1 kg mass by 1 m/s in 1 s.

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

where are the vectors ?
