The answer is - A sled sliding down the hill has higher kinetic energy.
Kinetic energy: It is a measure of the work done by an object based on its motion. Simple activities such as walking, jumping, throwing, and falling involve kinetic energy.
What is the S.I. unit of kinetic energy?
As per the kinetic molecular theory of matter, ‘All matter is made up of constantly moving particles, thus they possess kinetic energy.
Therefore, any substance in motion also has some kinetic energy.
The SI unit of kinetic energy is the Joule, which is equal to [tex]1 kg.m^2.s^-^2.[/tex]
Now, a sled resting on the top of the hill is at the rest and is not in motion while the sled sliding down the hill is in constant motion. As we know, a moving substance has higher kinetic energy than a substance at rest, thus, a sled sliding down the hill possesses higher kinetic energy.
