Cart Motion and Mass Analysis

The video tutorial discusses a scenario where an open cart rolls on a level surface during a rainstorm. As rain accumulates in the cart, the video explores how the cart's speed is affected. Various options are considered, focusing on the conservation of momentum. The analysis concludes that as the cart's mass increases due to rain, its speed decreases to conserve momentum.

What is the initial condition of the cart in the scenario?

• The cart is moving downhill.

• The cart is rolling on a level surface.

• The cart is stationary.

• The cart is moving uphill.

Which of the following is NOT a listed option for the cart's speed change?

• Decrease due to conservation of mechanical energy.

• Increase due to conservation of momentum.

• Remain the same due to perpendicular rain.

• Increase due to friction.

What principle is primarily used to analyze the cart's motion?

• Conservation of energy

• Conservation of momentum

• Conservation of mass

• Newton's second law

How does the mass of the cart change as it collects rain?

• The mass decreases.

• The mass remains constant.

• The mass increases.

• The mass fluctuates.

What happens to the cart's velocity as its mass increases?

• The velocity decreases.

• The velocity remains constant.

• The velocity increases.

• The velocity fluctuates.

Why must the cart's velocity decrease as its mass increases?

• To conserve energy.

• To conserve momentum.

• To conserve speed.

• To conserve mass.

What is the final conclusion about the cart's speed?

• The speed decreases due to conservation of momentum.

• The speed fluctuates randomly.

• The speed remains the same.

• The speed increases due to added mass.
