The machine as shown has \(2\) rods of length \(1\, m\) 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 \(2\, kg\) weight moves up and down. If the roller is moving towards right at a constant speed, the weight moves up with a
- A constant speed
- B decreasing speed
- C increasing speed
- D speed which is \(\frac{3}{4}\,th\) of that of the roller when the weight is \(0.4\, m\) above the ground
