What is a resistor that decreases as temperature increases

An astronaut on the planet Trappist-1b tosses a rock horizontally with a speed of 7.95m/s. The rock falls through a vertical distance of 2.35m and lands horizontal distance of 9.57m from the astronaut.

A man pushes an 250-N crate at constant speed a distance of 30.0 m upward along a rough slope that makes an angle of 60° with the horizontal. The work done by the force of gravity is:
