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.

  • Estimated Weight: 165lbs = 74.83kg

  • Stride: .748m per stride


Momentum beretta 92s
Momentum: Beretta 92S YouTube

  • 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: YouTubeInelastic 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 YouTube

  • 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 YouTube (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 YouTube

  • 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

  • H = ½ g t2

  • H = ½ 9.81 m/s2(3.34 sec)2

  • H = 55.78m

  • 15 times that shown in the video
