  1. Disproving Physics Disney Pixar “Up” Lauren Simcox & Becky Shaw

  2. Objective • Using mass, acceleration, velocity, time and force to disprove the scene where Mr. Fredrickson stops the house from falling off the blimp.

  3. Movie Scene • Russel sails the house towards the blimp. • Charles Muntz shoots some of the balloons holding the house, causing it to fall onto the blimp. • The house slides to the tail fin of the blimp, and Mr. Fredrickson stops the house from falling by holding a hose attached to the house. • www.youtube.com/watch?v=rV6rNqin4P8

  4. Calculations:

  5. National Geographic Results: ~ 300 balloons to make the house float ~ Each balloon could hold one tank of helium Volume of a Balloon: V= 4/3 πr3 =4/3 π(.1143m)3 = .00625m3 Number of Regular Balloons needed to float the house : 6 m3 = .00625 (X) m3 = 960 - # of balloons that one tank of helium can fill. 960 (300) = 288000 - regular sized balloons to float the house

  6. ~ Through estimation, we calculated the house to be 18800 ft2 ~ And for each ft2 the house weighs 45 lbs. Weight of the house: 18800 sq. ft. X 45 lbs./sq ft = 846000 / 2.2 = 384545.5 kg

  7. The distance the house slid: 41.8 ft - one side of the house X 4 - estimated distance 167.2 ft - the house slid Velocity the house moved at: V=d/t V = 167.2 / 7.85 - time estimated from movie V = 21 m/s

  8. How much force will Mr. Fredrickson need to stop the house from falling? Ft = m ( vf- vi ) F(7.85) = 384545.5 (0 - 21.3) F(7.85) = -8190819.15 F = -1043416.5 N of Force!

  9. Can Mr. Fredrickson Stop It ?!?!

  10. No he can't.... It would be impossible for him to use over 1 million newtons of force to stop the moving house sliding along the blimp.
