Projectiles: a Plane Flying at 70

question 18

Multiple Choice

Projectiles: A plane flying at 70.0 m/s suddenly stalls. If the acceleration during the stall is 9.8 m/s² directly downward, the stall lasts 5.0 s, and the plane was originally climbing at 25° to the horizontal, what is the velocity after the stall?

• A) 66 m/s at 17° below the horizontal
• B) 66 m/s at 17° above the horizontal
• C) 80 m/s at 37° below the horizontal
• D) 80 m/s at 37° above the horizontal

Same Direction

Indicates movement or trend in parallel or consistent alignment with another.

Model Depicted

A representation of a system or phenomenon used to predict or explain real-world behavior.

Slope

A measure of the steepness or inclination of a line, often represented as the ratio of the vertical change to the horizontal change between two points on the line.
