Suppose that when launching an 800-kg roller coaster car an electromagnetic propulsion system exerts a force of 5.7x^2 1.5x newtons on the car at a distance x meters along the track. Use Exercise 31(a) to find the speed of the car when it has traveled 60 meters. | Numerade

🚀✨ MHD: Magnetic Hydrodynamics — The Hidden Propulsion of the Future ✨🚀 Most people think of propulsion as burning fuel. But Magnetohydrodynamics (MHD) changes the game — using magnetic fields electrically conductive fluids or plasmas to generate thrust without moving parts. ⚡ How It Works: MHD drives run an electric current through an ionized medium — plasma, liquid metal, or even seawater. This current interacts with a powerful magnetic field, producing Lorentz forces that push the fluid and
