Transcribed Image Text:**Problem Statement:**
An alien on the planet Zoota walks up to a meteor on the ground on a level field and kicks it with a velocity of 42.5 meters per second at an angle of 30.0 degrees above the horizontal. If the rock lands 105 meters away, answer the following questions:
A) How long was it in the air?
B) What is the gravitational acceleration at the planet's surface?
**Explanation:**
This problem involves projectile motion. To solve it, we must decompose the initial velocity into horizontal and vertical components and use kinematic equations. The horizontal distance traveled (range) and the time of flight are linked, which helps determine the gravitational acceleration on the planet Zoota.
