Aconducting sphere of radius r carries positive charge q. calculate the amount of work that would be required to move a small positive test charge q0 slowly from r=5r to r=3r. assume that the presence of q0 has no effect on how the charge q is distributed over the sphere.
express your answer in terms of the electric constant ϵ0 and some or all of the variables q, q0, and r.

i'm assuming you're asking for the elevator's final velocity.
consider the following equation:
vf = vi + aδt
vf is the final velocity.
vi is the initial velocity.
a is the acceleration.
δt is the amount of elapsed time.
vi = 12.60m/s
a = -3.60m/s²
δt = 2.97s
substitute the terms in the equation with the given values and solve for vf:
vf = 12.60 - 3.60×2.97vf = 1.91m/s
