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

speed which is `3/4th` of that of the roller when the weight is 0.4 m above the ground

B

constant speed

C

decreasing speed

D

increasing speed
