Motion Along a Straight Line - Parachutist Height Physics Problem

Learn to solve a complex physics problem involving a parachutist's descent through a detailed 24-minute video tutorial that breaks down motion along a straight line. Calculate the total time in the air and initial height by analyzing two distinct phases of motion: free fall for the first 50 meters followed by decelerated motion with an open parachute until landing at 3.0 m/s. Master the application of kinematics equations while considering changing acceleration conditions and final velocity constraints to determine both the duration of the fall and the initial height of the jump.
