  1. Anika Jäckel, Sherry Gu, and Jahnavi Singh Corkscrew:A Physics Problem

  2. The Problem When standing thirty meters away, the top of the corkscrew is at an angle of 35° at an eye height of 172 centimetres

  3. The train takes twenty seconds to reach the top.

  4. Suppose the train weighs fifteen tonnes and the ride uses an engine with five hundred horse power to pull the train up.

  5. What is the efficiency of the engine?

  6. The Solution h = dtanθ + heye height h = (30) tan(35) + 1.72 h = 21 + 1.72 h = 22.7 m Engine = 500 hp t = 20s m = 15 tonne Efficiency = Wo x 100% WI Efficiency = (15 000) (9.8) (22.7) x 100% (500) (746) (20) Efficiency = 3 336 900 x 100% 7 460 000 Efficiency = 45% The engine has an efficiency of 45%. h 35° 172cm 30 m
