3. The figure shows a block on a frictionless ramp; a cord attached to the block can pull on the block with a force parallel to the ramp. Here are three situations:
1. The block moves up the ramp with speed increasing at the rate of 2 m/s².
2. The block moves down the ramp with speed decreasing at the rate of 2 m/s².
3. The block moves down the ramp with speed increasing at the rate of 2 m/s². Rank the three situations according to the tension in the cord, greatest first. () indicates a tie.
