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 :
constant speed
decreasing speed
increasing speed
speed which is th of that of the roller when the weight is 0.4 m above the ground
From
dx /dt = constant
As with motion of roller , x decreases
dy/dt decreases
weight will move with decreasing speed
Option 1)
constant speed
Option 2)
decreasing speed
Option 3)
increasing speed
Option 4)
speed which is th of that of the roller when the weight is 0.4 m above the ground
