Three projectiles; A, B,and C, are launched as shown: The arrows represent the initial velocities of the projectiles drawn to scale All three projectiles eventually land on the level ground. Neglect air resistance: Which projectile has the greatest initial speed? Which projectile has the smallest speed immediately before impacts the ground? Which projectile has the greatest initial horizontal component of the velocity? Which projectile has the smallest final horizontal component of the velocity? Which projectile has the greatest acceleration at the top point of the flight? Which projectile has the greatest speed at the top point of the flight?

Projectile Motion Multiple Choice 1. Suppose a rescue airplane drops a relief package while it is moving with a constant horizontal speed at an elevated height. Assuming that air resistance is negligible, where will the relief package land relative to the plane? a. below the plane and behind it. b. directly below the plane c. not enough information to determine d. below the plane and ahead of it 2. Which velocity is always constant? a. none, they are always changing b. both vertical and horizontal c. only vertical d. only horizontal 3. The horizontal and vertical components of motion are completely________of one another. a. unknown b. imposed c. dependent d. independent 4. In which direction does an object accelerate? a. horizontal only b. vertical only c. both directions d. neither directions Short Answer 5. What angle is the optimal angle for maximum range? 6. What trig function coincides with the horizontal (x) motion? ...the vertical (y) motion? 7. What was the first use of biological warfare?
