A weight lifter struggles but manages to keep a heavy barbell above his head. Occasionally he slips and the barbell starts to fall downward, but he always recovers. Compare the force exerted by the weight lifter on the barbell to that exerted by the barbell on the weight lifter. Which of the following are correct?
The force exerted by the weight lifter on the barbell is bigger than the force exerted by the barbell on the weight lifter.
The force exerted by the weight lifter on the barbell is smaller than the force exerted by the barbell on the weight lifter.
The force exerted by the weight lifter on the barbell is smaller than the force exerted by the barbell on the weight lifter when the barbell falls downward. The force exerted by the weight lifter on the barbell is bigger than the force exerted by the barbell on the weight lifter when the weight lifter recovers.
The force exerted by the weight lifter on the barbell is equal to the force exerted by the barbell on the weight lifter.
The force exerted by the weight lifter on the barbell is bigger than the force exerted by the barbell on the weight lifter when the barbell falls downward. The force exerted by the weight lifter on the barbell is smaller than the force exerted by the barbell on the weight lifter when the weight lifter recovers.
A yo-yo is made from two uniform disks, each with mass M/2 and radius R, associated by a light axle of radius r(R>r). Since the axle is nearly mass less, the total mass of the yo-yo is M. A light, thin string is wound several times around the axle.
