Question

In this video, you will analyze the motion of a fan cart. Initially, the cart is held in place by a spring; once the cart is released, it accelerates forward. The main goal of the activity is to compare the acceleration of the car obtained from kinematics with that obtained from Newton's second law.

Before you start taking the measurements, let's make sure you understand the concepts and the calculations involved. Click play to watch the video below (text description of video), then answer the questions that follow.

Explanation / Answer

Since the video is not available, we are assuming the cart is on a horizantal table. So before cutting the spring the forces that are holding the cart in place are Normal force from spring and Tension in the spring.
