Answer:

spring scale and meter stick

Step-by-step explanation:

The work done by a force of friction can be calculated as the force of friction times the distance. So, we need to measure the force done and the distance traveled. Therefore, the answers are spring scale and meter stick, because the spring scale measures force and the meter stick measures distance.
