A cart is given a slight push along a near frictionless track (as shown in the video below).
After the push, the cart is observed to move with a near constant velocity . Determine its location after 3 seconds.
You need to predict the location of the cart using the information provided and any information that you can collect or assume.
We can compute the final location,
You might use the video to define an origin such that the initial position of the cart is . With that new information, the final location of the cart can be computed exactly,
Notice that -position of the cart remained unchanged because all the motion of the cart was in the -direction.
