    According to newton's 3rd law of motion,

    For every action, there is equal and opposite reaction. So if we move a body against a rough surface, there were be reaction against the force applied.

    So using conservation of energy, we know:

    Work done to move a body = Work done against Friction

    So, Force applied * distance moved = coefficient of Friction * Normal Reaction * distance moved

    For a body moving against a normal surface, Normal Reaction (R) = mg

    or, mass * acceleration * distance (s) = ∪ * R * distance (s)

    or, mass * (v^2/2s) = ∪ * mass * gravity

    Now, s = stopping distance = v² / 2∪g

    so, using given value,∪=0.05,

    s = v2/2*0.05*g

    We know, g = 10, so s = v² / (2*0.05*10) = v²

    where v = initial velocity
