Question

In this lab you will use videos of a fan cart on a frictionless track. The mass of the fan cart is claimed to be 275.2 g.

The fan is set at different speed pushing air backward and the resultant pushing force of the air on the cart can be measured.


The initial speed of the cart before being let go is zero
The time during which the fan is working can be measured using frame count and frame rate


The final speed when the fan is turned off can be measured using a ruler and the frame counter

Answer 1

The subject of this question is Physics. The student is investigating the force exerted by the fan on a frictionless cart and will measure the pushing force of the air on the cart.

Step-by-step explanation:

The subject of this question is Physics.

In this lab, the student is investigating the force exerted by the fan on a frictionless cart. The mass of the fan cart is claimed to be 275.2 g. The student will measure the pushing force of the air on the cart by observing the final speed of the cart when the fan is turned off.

To conduct the experiment, the student will measure the initial speed of the cart before releasing it, the time during which the fan is working, and the final speed of the cart when the fan is turned off.
