1 Projectile Motion What is a projectile? Regardless of its path, a projectile will always follow these rules: 1. A horizontally launched projectile moves both horizontally and vertically and traces out a parabolic trajectory. (Trajectory: The parabolic path of a projectile.) 2. The horizontal and vertical motions of a projectile are completely independent of one another. a. In the absence of air resistance, there is no net horizontal force on the projectile; therefore the projectile travels with a constant horizontal velocity. b. In the absence of air resistance, gravity is the only vertical force on the projectile; therefore the projectile travels with a uniformly accelerated vertical motion. Every second, the vertical velocity of the projectile changes by 9.8 m/s (10 m/s)

4 3. Horizontal and vertical motion are completely independent of each other. Therefore, the velocity of a projectile can be separated into horizontal (v x ) and vertical components (v y ). v x = velocity in the xdirection v y = velocity in the ydirection 4. For a projectile beginning and ending at the same height, the time it takes to rise to its highest point equals the time it takes to fall from the highest point back to the original position. 5. For a projectile beginning and ending at the same height, the initial speed is equal to its final speed.
5 Questions: 1. A projectile is launched at an angle into the air. If air resistance is negligible, what is the acceleration of its vertical component of motion? Of its horizontal component of motion? 2. At what part of its trajectory does a projectile have minimum speed? 3. Supposing a snowmobile is equipped with a flare launcher that is capable of launching a sphere vertically (relative to the snowmobile). If the snowmobile is in motion and launches the flare and maintains a constant horizontal velocity after the launch, then where will the flare land (neglect air resistance)? a. in front of the snowmobile b. behind the snowmobile c. in the snowmobile 4. 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? 5. A hunter fires a gun at the same time a monkey drops a coconut as shown below. Where should the hunter aim to hit the coconut?

How far from the base of the cliff does the ball land? C. What is the vertical velocity of the ball just before it strikes the ground? D. What is the horizontal velocity of the ball just before it strikes the ground? 4. You are trying to roll a ball off an 1.8 m high table to hit a target on the floor 2.0 m from the table's edge. With what speed should you roll the ball?
8 Projectiles Launched At An Angle Let s do one example to illustrate this concept: A ball is thrown with a velocity of 5 m/s at an angle of 60 above the horizontal. V yf =0 at top v yi = 4.36 m/s v xi Separate into x and y components. v yi 5 m/s 60 o v xi
9 Magic Chart Equations d t v I v F a d y = ½ (v yi + v yf ) t x x x x NO d y = v yi t t 2 x x x NO x V yf = v yi t NO x x x x V yf 2 = v yi d x NO x x x Example: A ball is thrown with a velocity of 8 m/s at an angle of 30 above the horizontal. 1. Calculate the time it takes the ball to reach the apex? (time up ) 2. Determine the total time the ball is in the air? (time total ) 3. How high does the ball go? (maximum height) V xi = initial horizontal velocity V yi = initial vertical velocity V fy = final vertical velocity 4. How far (horizontally) does the ball go? (range)
