Suppose you are an engineer, and you are asked to measure the force on a supporting beam of a bridge. you measure it to be 50,067 lbs, but you know that your scale is only precise to ±400 lbs. how do you record this measurement in your final report to the client? (keep in mind that you want to find the perfect way to express the number to give an idea of how precise it is.) click the above link to submit a three sentence description, which includes:

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct?

(c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
