5. An object has a mass of 10 kg. It is just sitting on a flat surface. What is the normal force it experiences? (I never taught you a direct equation for Normal Force - what does
normal force oppose here?) (Show your work)

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

like poles repel so keep pushing north to north and repels funny to see this

i think the answer is a, hope this : )
