curving a bullet
Curving A Bullet
  • Wanted (6/11) Movie CLIP - Wesley\'s First Curved Bullet (2008) HD - YouTube
video breakdown
Video Breakdown
  • Mr. X runs out a hallway window from a skyscraper and shoots at a man on a building across the street.
  • While in the air he shoots 3 shots.
  • He lands about 12 feet below his original height.

Estimations
  • Secondary Roof
    • 400 ft = 121.92m
  • Height Mr. X drops
    • 12 ft = 3.66 m
calculating velocity
Calculating Velocity
  • OSHA Minimum Requirement (Office)
    • 61ft = 18.59m
  • 3 doorways 18.59 X 3 = 55.78m
  • OSHA Minimum Requirement (Elevator) 1.74m
  • 55.78 + 1.74
  • Total distance 131.89m in 28 sec
calculating velocity cont
Calculating Velocity (Cont)
  • Velocity = Distance / Time
  • 57.53 / 6.3 = 9.13 m/s
    • 20.42 mph
  • Fastest recorded speed was 10.35 m/s

Momentum: Beretta 92S
  • 2 shots
  • Muzzle velocity: 1250 ft/s = 381m/s
  • Mass: 970g = .97kg
  • Momentum = Mass X Velocity
  • M= .97 X 381 = 369.57

  • 1 shot
  • Muzzle Velocity: 1000ft/s = 304.8m/s
  • Mass: 2.98lbs = 1.35kg
  • Momentum = Mass X Velocity
  • M= 1.35 X 304.8 = 411.99
conservation of momentum inelastic collisions
Conservation of Momentum:Inelastic Collisions
  • (m1 + m2)V = (m1v1f) + (m2V2f)
  • (mass man/gun/bullet)man’s velocity mass/velocity of bullet mass/velocity man/gun
conservation of momentum inelastic collisions1
Conservation of Momentum: Inelastic Collisions
  • Finding the final velocity to use for projectile motion
  • Information for equation:
    • Mass of man/gun/bullet: 74.84kg
    • Mass of Bullets: .2kg each (3 bullets)
    • Mass of first gun (2 shots): .97kg
    • Mass of second gun (1 shot): 1.35kg
    • Velocity of Man running: 9.13m/s
    • Muzzle Velocity first gun: 381m/s
    • Muzzle Velocity of second gun: 304.8m/s

Conservation of Momentum: Inelastic Collisions: Equation (m1 + m2)V = (m1v1f) + (m2V2f)(mass man/gun/bullet)man’s velocity mass/velocity of bullet mass/velocity man/gun

  • First Shot
  • (74.84 + .2 + .2 + .2 + 2.32)9.13 = .2(381) + (74.84 + 2.32)vf
  • 709.95 = 76.2 + 77.16vf
  • Vf = 8.21m/s
  • Second Shot
  • (74.84 + .2 + .2 + 2.32)8.21 = .2(381) = (74.84 + 2.32)vf
  • 636.77 = 76.2 + 77.16vf
  • 560.57 = 77.16vf
  • Vf = 7.27 m/s
  • Third Shot
  • (74.84 + .2 + 2.32)7.27 = .2(304.8) + (74.84 + 2.32)vf
  • 562.41 = 60.96 + 77.16vf
  • 501.45 = 77.16vf
  • Vf = 6.50m/s
projectiles time it should take to jump the distance
Projectiles: Time it should take to jump the distance
  • d = vxt because horizontal velocity is constant
  • City of Chicago street measurements:
    • D = 100 ft = 30.48m
  • 30.48m = 9.13m/s x time
  • t = 3.34s
projectiles how much height he would lose in that time
Projectiles: How much height he would lose in that time
  • H = ½ g t2
  • H = ½ 9.81 m/s2(3.34 sec)2
  • H = 55.78m
  • 15 times that shown in the video
