Question

question 3
determine which of the following have balanced forces acting on them.
a cat sleeping in a chair
a rocket speeding up as it launches into space
a mug resting on a bench
a basketball speeding up as it falls through the air
im not sure

Explanation:

Balanced forces occur when the net force on an object is zero, meaning the object is either at rest or moving at a constant velocity.

• A cat sleeping in a chair is at rest. The force of gravity pulling it down is balanced by the normal force from the chair pushing it up.
• A rocket speeding up as it launches has an unbalanced force (thrust greater than gravity and air resistance) causing acceleration.
• A mug resting on a bench is at rest. Gravity (downward force) and the normal force (upward force from the bench) are balanced.
• A basketball speeding up as it falls has an unbalanced force (gravity acting on it, causing acceleration as air resistance is usually less than the gravitational force for a falling basketball in the initial stages).

Answer:

A. A cat sleeping in a chair
C. A mug resting on a bench
