A small sphere carries a charge of 120microcoloumb calculate the magnitude and direction of a force which it exerts on a second small sphere carrying a charge of - 300 microcoloumb if the distance between them is 30

grav potential energy

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

i'm on my way to history not a mistory.

the maxium height is 34m/s
