The machine as shown has $\displaystyle 2$ rods of length $\displaystyle 1$ m connected by a pivot at the top. The end of one rod is connected to the floor by a stationary pivot and the end of the other rod has a roller that rolls along the floor in a slot. As the roller goes back and forth, a $\displaystyle 2$ kg weight moves up and down. If the roller is moving towards right at a constant speed, the weight moves up with a :
