In the diagram below, two objects of the same size and mass are released from rest at the starting position. Object 1 was released before Object 2 was released. The diagram below shows the positions of Objects 1 and 2 a short time after both were released.

To answer this question, we need to understand the concepts of kinetic energy and potential energy.
Kinetic energy is the energy possessed by an object due to its motion. It depends on the mass of the object and its velocity. The equation for kinetic energy is KE = 1/2 * m * v^2, where m represents the mass of the object and v represents its velocity.
Potential energy, on the other hand, is the energy stored in an object due to its position or state. It depends on the height or distance an object is lifted or moved against a force. In this case, we can consider gravitational potential energy. The equation for gravitational potential energy is PE = m * g * h, where m represents the mass of the object, g represents the acceleration due to gravity (9.8 m/s^2 on Earth), and h represents the height of the object from a reference point.
When you ride a slingshot and reach the top of the shot, your potential energy is at its maximum because you are at the highest point. At this moment, your kinetic energy is at its minimum because your velocity is momentarily zero. As you start to descend, your potential energy decreases while your kinetic energy increases.
Therefore, the correct answer to the question is:
The kinetic energy is less than the potential energy.
