  1. Alluda Majaka అల్లుడా మజాకా • Lindsay Krause & Ellen Sederdahl

  2. Video Explanation • Chiranjeevi is being chased by over a dozen men on either horseback or in Jeeps • He steals one of their horses and continues to be chased • As he and the horse continue down the road, a tractor trailer completely blocks the intersection • In order to elude his followers, he gets the horse to fall, to slide underneath the inconvenient tractor trailer, and get back up again, continuing his chase

  3. Physics Explanation • Find the force of friction • Use distance formula to find the stopping distance in the movie • Use force of friction to determine acceleration • Use acceleration to determine the time it should have taken the horse and Chiranjeevi to stop • Substitute the new time into the distance formula to find the distance they should have traveled

  4. Estimations • Chiranjeevi • 5’9” • Average weight • 165 lbs = 75 kg • Horse • Average weight of riding horse • 1,200 lbs = 544kg Total Weight 75 kg + 544 kg = 619 kg

  5. Estimations Chiranjeevi begins at a distance of approximately 4 cars (3 cars and one car-sized space between the first car and the tractor trailer) Approx. 1 ft between each car • Length of Car • Approximately 6.5 tires • 1 tire = 20 approx. inches 20 in.

  6. Calculations 6.5 (length of one car in tires) X 20 (tire length in inches) 130 inches per car 130 (car length) X 4 (number of cars + car sized space) 520 total inches of cars & space (43.3 feet) 520 (total inches of cars & space) + 24 (distance between the three cars) 544 = 13.817 meters Distance traveled before fall: 13.817 meters

  7. Calculations Time traveling before fall: 3:64 seconds Velocity before fall Velocity = distance time Velocity = 13.8 m 3.63 sec Velocity = 3.8 m/s

  8. Calculations Coefficient of friction (µ) Force of Friction Fk= µ·Fnorm = µ·m·g Fk = .4(619 kg)(9.81 m/s²) Fk = 2,429 N (brick and sand) µ = .4

  9. Calculations Stopping Distance d = ½(vi + vf)t d = ½(3.8 m/s)(4.54 sec) d = 8.6 meters

  10. Calculations Time horse and Chiranjeevi should have stopped Fk = m·a -2,429 = (619 kg)a a = -3.924 m/s 0 a = vf - vi t t = -vi a t = -3.8 -3.924 t = 0.97 seconds

  11. Calculations Distance Chiranjeevi and horse should have stopped d = ½(vi + vf)t d = ½(3.8 m/s)(0.97 sec) d = 1.84 meters

  12. Conclusion 8.6 m – 1.84 m = 6.76 meters too long 4.54 sec – .97 sec = 3.57 seconds too long In the film Chiranjeevi and the horse traveled about 8.6 meters in 4.54 seconds as they were sliding. However, in reality they should have traveled only 1.84 meters in .97 seconds. In the movie Chiranjeevi and the horse traveled 6.76 meters too long and 3.57 seconds too long. 1.84 meters = 6.0 ft 8.6 meters = 28.2 ft
