Projectile Motion: Quiz(1) 1) The velocity of a projectile at launch has a horizontal component vn and a vertical component vy. Air resistance is negligible. When the projectile is at the highest point of its trajectory, which of the following show the vertical and horizontal components of its velocity and the vertical component of its acceleration? Vertical Horizontal Vertical Velocity Velocity Acceleration (A) Vv Vx o (B) Vv 0 O (C) 0 Vx 0 ( D ) 0 0 gravity (E) 0 Vx gravity 2) If a projectile is launched from the ground which of the following periods of angles will result in the same horizontal range? A) 0 = 450, 0 =300 B) 0 = 600, 0 =450 DOE = 0 '006 = 0 (3 (D)0 = 300, 0 =600 E) 0 = 750, 0=250 3) An airplane pilot is moving with a velocity V and drops a package. In the absence of air resistance where is the package relative the airplane at the moment it hits the ground? A) Behind the airplane B) In front of the airplane () Directly below the airplane D) Cannot be determined without how high the plane is E) Cannot be determined without knowing the distance traveled by the airplane 4) In a lab experiment you need to predict where a steel ball will land when it rolls off a table. The ball rolls off the table that is 0.8 meters high. If the ball travels on the table with a constant velocity and travels 1.2 meters in 3.1 seconds. How far from the base of the table will the steel ball land
