Question

Timmy has fallen in a well! Firefighters are rescuing Timmy by securing him to a harness and pulling him upward. Timmy considers his situation as he is being pulled upward at a steady speed. Which statement below most correctly describes his situation?

a) Timmy is in equilibrium.

b) Timmy is accelerating downward.

c) Timmy is accelerating upward.

d) Timmy is at rest.

Answer 1

Timmy is accelerating upward.

Step-by-step explanation:

The correct answer is c) Timmy is accelerating upward. When Timmy is being pulled upward at a steady speed, it means his velocity is increasing. Velocity is a vector quantity that includes both speed and direction. Since Timmy is moving upward, his velocity is increasing in the upward direction, which means he is accelerating upward.
