Answer:
Usually, zeroes are found to the right of a decimal point in significant numbers if you have something like (exaggerated example of course), which is when you have a number that is very very close to the integer before it, but isn't that integer.
By balancing the force, we get :
100 - Frictional Force = ma
100 - μmg = ma
100 - μ(5)(10) = (5)(15)
50μ = 25
μ = 0.5
Distance travelled by box in 5 seconds is :
Hence, this is the required solution.
