Basket is tied to rope and it is stopped by fixed clamp

Reference no: EM13671665

1) a) In a piston is locked in place and the cylinder is placed in a boiling water, the temperature, pressure, internal energy are all increase

b) If a piston is being pushed inward, would it have the same answer as above

2) If the system is a basket,

The basket is tied to a rope and it is stopped by a fixed clamp when it is falling down, I know there is initial KE however how come initial work is negative. Is not force and displacement are in the same direction, so work must be positive?
