To determine the average time of fall, you need to measure the time three times and calculate the average. Let's assume you measure the following times: t1, t2, and t3.
The average time of fall (t_avg) can be calculated by summing the measured times and dividing by the number of measurements:
t_avg = (t1 + t2 + t3) / 3
Next, you can use equation (1) to determine the terminal velocity (vT). The equation is not provided in your question, so I cannot give you the exact formula to use. However, the terminal velocity is typically determined by factors such as mass, gravitational acceleration, and drag coefficient.
If you can provide the equation or the necessary parameters, I can assist you further in calculating the terminal velocity.
