Responses
The kinetic energy is increasing.
The kinetic energy is increasing.
The kinetic energy is decreasing.
The kinetic energy is decreasing.
The kinetic energy is staying the same.
The kinetic energy is staying the same.
The kinetic energy goes down and then up.
The kinetic energy is staying the same.
Based on the given options, the correct answer is: The kinetic energy is decreasing.
To determine what is happening to the cart's kinetic energy in section E, we need to understand the factors that affect kinetic energy. Kinetic energy is given by the equation KE = 0.5 * mass * velocity^2, where mass is the mass of the object and velocity is the magnitude of its speed.
In section E, if the velocity of the cart is increasing, then its kinetic energy is also increasing. This is because kinetic energy is directly proportional to the square of velocity. So, if the cart is speeding up in section E, its kinetic energy is increasing.
Therefore, the correct answer is:
"The kinetic energy is increasing."
