**Will somebody please help me with a physics problem?**

At work we have very heavy carts. The floor is in terrible shape. Management knows that they need to fix the floor but don't know if it will be cost effective. I.E. money spent on floor vs. increased production.

I want to make a spreadsheet. I don't know the math and I need your help.

I want to have 3 variables

The mass of the cart. the diameter of the wheel, and the size of the bumps on the floor will all change. I want to find out how many Newtons it takes to push this trolley.

M mass

D dia of wheel

H height of bump on floor

step 1

I need the math formula of how many Newtons will it take to get this trolley moving from a stationary position?

step 2

How many Newtons will it take to push this trolley over a bump on the floor? H

please see this drawing
