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 πr 3 =4/3 π(.1143m) 3 =.00625m 3 Number of Regular Balloons needed to float the house : 6 m 3 =.00625 (X) m 3 = 960 - # of balloons that one tank of helium can fill. 960 (300) = 288000 - regular sized balloons to float the house

6. Weight of the house: 18800 sq. ft. X 45 lbs./sq ft = 846000 / 2.2 = 384545.5 kg ~ Through estimation, we calculated the house to be 18800 ft 2 ~ And for each ft 2 the house weighs 45 lbs.

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

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.
