If the direction of v⃗ ′ is reversed, so both charges are moving in the same direction, what is the magnitude of the magnetic forces that the two charges exert on each other?

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 think the answer is tomato juice? not entirely sure though
