Question 1

Two workers, Liam and Noah, try to move identical heavy crates, Crate A\text{Crate A}Crate A and Crate B\text{Crate B}Crate B, which are initially at rest on the floor.

  • Liam pushes horizontally against Crate A\text{Crate A}Crate A with a large force, but the crate does not move because it is wedged against a wall.
  • Noah lifts Crate B\text{Crate B}Crate B vertically upwards from the floor and places it on a tall shelf.

Which worker does the most work on their crate, and which crate gains the most energy?

A

Liam | Crate A\text{Crate A}Crate A

B

Liam | Crate B\text{Crate B}Crate B

C

Noah | Crate A\text{Crate A}Crate A

D

Noah | Crate B\text{Crate B}Crate B
