An electric motorcycle designer uses a motor with a torque output that increases by 15% each year due to improvements. If the initial torque is 85 N·m in year one, what will it be at the end of the third year (rounded to the nearest whole number)?
["Electric Motorcycle Torque Growth: A 15% Annual Increase Explained", "Electric motorcycle technology continues to advance rapidly, and one of the most exciting developments is the consistent growth in motor torque output. Unlike internal combustion engines, electric motors deliver instant torque with precision, making them ideal for dynamic performance. A pioneering electric motorcycle designer is pushing this technology forward with a compelling innovation: a motor whose torque increases by 15% each year through ongoing engineering improvements.", "Starting from an initial torque of 85 N·m in year one, understanding how this growth compounds annually is essential for performance forecasting and market expectations. With each year, the torque grows by 15%—a multiplicative increase that creates exponential progress over time.", "Let’s break down the evolution of torque year by year:", "- Year 1: Base torque = 85 N·m\n- Year 2: Torque increases by 15%\n [\n 85 \ imes 1.15 = 97.75\ \ ext{N·m}\n ]\n- Year 3: Torque increases by another 15% from Year 2’s output\n [\n 97.75 \ imes 1.15 = 112.4125\ \ ext{N·m}\n ]", "After rounding to the nearest whole number, the torque at the end of the third year reaches 112 N·m.", "This steady 15% annual increase highlights the rapid progress in electric motor design—critical for enhanced acceleration, hill climbing, and rider experience. As engineers refine motor efficiency and battery integration, future models will likely exceed even these projections. The growing torque trend underscores why many are turning to electric motorcycles as the future of urban mobility and performance riding.", "Conclusion: By the third year, with consistent 15% annual torque growth starting at 85 N·m, the motor delivers approximately 112 N·m of torque—marking a significant leap in electric propulsion power."]
