Final answer:
The question asks for the instantaneous velocity of a cart at a specific point, which cannot be calculated without additional information such as time taken or an equation of motion.
Step-by-step explanation:
To calculate the instantaneous velocity of the cart at 96 centimeters from the start, we require additional information, such as the time taken to reach that point, or an equation of motion that describes the cart's velocity as a function of its displacement.
Unfortunately, the information provided does not directly relate to the specific question about the cart's instantaneous velocity at 96 centimeters from the start. However, an equation for velocity as a function of distance, or data on time and acceleration can be used to find instantaneous velocity using kinematic equations.
