Average Velocity Calculation in a Lab Experiment

How can we calculate the average velocity of a cart in a lab with constant acceleration?

Can you provide the average velocity of the cart for each fan speed?

Answer:

Without specific data, we cannot provide numerical values for the average velocity of a cart at different fan speeds. Average velocity is calculated by dividing the total displacement by the time taken, and a cart with a higher fan speed would typically have a greater average velocity.

To calculate the average velocity of a cart for different fan speeds in a lab with constant acceleration, we would typically use the formula average velocity = (initial velocity + final velocity) / 2 when acceleration is constant. However, without specific values for initial and final velocities or the distance and time over which the cart travels, we cannot provide exact numbers for the average velocities at low, medium, and high fan speeds.

As a general concept in physics, the average velocity is directly proportional to the fan speed when acceleration is constant if we assume starting from rest. Therefore, a cart with a higher fan speed will have a greater average velocity than one with a lower fan speed.

If experimental data were provided, you would calculate the average velocity by measuring the total displacement of the cart (the change in position from the start to the end) and dividing it by the total time it took to travel this distance. If only the time is given, you could compute the average velocity using the kinematic equation for uniformly accelerated motion.
