Learn to solve a multi-part physics problem involving the kinematics of a light-rail commuter train through this 10-minute tutorial from Dot Physics. Work through Chapter 2 Problem 23 from OpenStax College Physics, which requires calculating time intervals and acceleration values for different scenarios. Solve for the time needed for a train to reach its top speed of 80.0 km/h from rest with an acceleration of 1.35 m/s², determine the stopping time from top speed with a deceleration of 1.65 m/s², and calculate the emergency deceleration rate when the train stops from 80.0 km/h in 8.30 seconds. Practice unit conversions between km/h and m/s while applying kinematic equations to real-world transportation scenarios.
