1. Homework Statement _> Suppose the 2.0kg model car is initially at rest at x=0 and F is the net force acting on it. Use the work energy theorem to find the speed of the car at (a) x=3.0m, (b) x=4.0m, and (c) x=7.0m...

Ohh since the tension and the displacement are in the positive direction, that makes the work done positive because they are opposing the natural acceleration of gravity?

1. The Problem: An elevator is hoisted by its cables at a constant speed is the total work zero, negative, or positive? 2. Homework Equations : g= -9.81m/s2 3. The Attempt at a Solution I'm thinking that since the weight of the elevator is in downward direction along with the acceleration of...
