Approach Analysis
The question asks which physical quantities will be directly measured in the lab to deduce a ball's launch speed, given a list of possible quantities. We'll evaluate each option one by one and explain why it would or would not be directly measured. Option: The ball's launch velocity - Direct measurement: In many setups, the launch velocity is not measured directly at the moment of launch; instead, other quantities (like time-of-flight, distance, or sensor readings) are measured and used to infer the launch speed. Thus, this option is not typically a quantity you would directly measure in this experiment. Option: The maximum angle the pendulum swings out - Direct measurement: If a pendulum is part of the launcher mechanism, you might observe how far the pendulum swings during calibration or setup. However, the maximum swing angle is not necessarily used to deduce the ball's launch speed i......Login to view full explanation
