Points A (at (10,10) m) and B (at (1, 1) m) are in a region where the electric field is uniform and given by N/C. What is the potential difference

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

the force on the thing and the distance the force moves the thing

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
