2019 #4 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers question #4 from the 2019 AP Physics One exam. It begins with an introduction to the problem, which involves a motor lifting a block at constant speed. Part A requires determining an expression for mechanical power, which is solved by equating the force of tension to the force of gravity. Part B involves modifying the circuit to decrease the time interval by adding a resistor, with the solution focusing on increasing the current through the motor. The tutorial emphasizes understanding mechanical power and circuit analysis.
