QUIZZES > PREVIEW ASSESSMENT LEC 02 QUIZ Preview Assessment Lec 02 Quiz Name: Lec 02 Quiz Instructions: Multiple Attempts: This Test allows multiple attempts. Force Completion: This Test can be saved and resumed later. Question Completion Status: Question 1 16 points Save A projectile is launched from a cliff at a 42 degree angle above the horizontal. It eventually reaches the ground below. This question is exclusively about the projectile while it is in free fall. It is in free fall from the instant after it leaves the launcher until the instant before it hits the ground. Where, along the trajectory of the projectile, is the kinetic energy of the projectile at its minimum value? Nowhere. At the point where it leaves the launcher. At the highest point of its motion. At the lowest point in its motion, its location immediately prior to hitting the ground. Question 2 16 points Save A projectile is launched from a cliff at a 42 degree angle above the horizontal. It eventually reaches the ground below. This question is exclusively about the projectile while it is in free fall. It is in free fall from the instant after it leaves the launcher until the instant before it hits the ground. Where, along the trajectory of the projectile, is the kinetic energy of the projectile zero? Nowhere. At the point where it leaves the launcher. At the highest point of its motion. At the lowest point in its motion, its location immediately prior to hitting the ground. Question 3 16 points Save A projectile is launched from a cliff at a 42 degree angle above the horizontal. It eventually reaches the ground below. This question is exclusively about the projectile while it is in free fall. It is in free fall from the instant after it leaves the launcher until the instant before it hits the ground. Where, along the trajectory of the projectile, is the potential energy of the projectile at its maximum value? Nowhere. At the point where it leaves the launcher. At the highest point in its trajectory. At the lowest point in its motion, its location immediately prior to hitting the ground. Question 4 16 points Save A projectile is launched from a cliff at a 42 degree angle above the horizontal. It eventually reaches the ground below. This question is exclusively about the projectile while it is in free fall. It is in free fall from the instant after it leaves the launcher until the instant before it hits the ground. Where, along the trajectory of the projectile, is the kinetic energy of the projectile at its maximum value? Nowhere. At the point where it leaves the launcher. At the highest point of its motion. At the lowest point in its motion, its location immediately prior to hitting the ground....
