(5) projectile motion

  1. 1. Projectile Motion
  2. 2. REVIEW or equations describing Free Falling bodies g = acceleration due to gravity = 9.81 m/s 2 Measured in downward direction
  3. 3. Projectile Motion: <ul><li>Assumptions: </li></ul><ul><li>Free-fall acceleration g is constant over the range of motion and is directed downward </li></ul><ul><li>The effect of air resistance is negligible. </li></ul><ul><li>The path of projectile, or trajectory is always a parabola. </li></ul>
  4. 4. Properties of a Projectile
  5. 5. Properties of Projectile Motion
  6. 6. Projectile Fired from the Origin
  7. 7. Sample Problem 1: <ul><li>A golfer strikes the ball which leaves the tee at an angle of 35 degrees to the horizontal with an initial speed of 40 m/s. Assume the course from tee to green is level determine: </li></ul><ul><li>(a) The time of flight </li></ul><ul><li>(b) The range </li></ul><ul><li>(c) The maximum height of the ball </li></ul>
  8. 8. Sample Problem 2: <ul><li>A baseball thrown horizontally from the edge of the top of a building 20 m above a level field lands 45 m away from the building. Calculate the initial speed. </li></ul>
