Answer
The layer of water decreases the friction between the sled and the slide. This is because water acts as a lubricant, allowing the sled to glide more smoothly down the slide.
Step 2
Calculate the gravitational potential energy of the rider at the top of the slide.

Answer
Using the formula for gravitational potential energy:
Ep=massimesgravitationalfieldstrengthimesheight
Substituting the known values:
Ep=62.5kgimes9.8N/kgimes16.0m=9800J
Step 3

Using the formula for kinetic energy:
Ek=0.5imesmassimes(speed)2
Substituting the known values:
Ek=0.5imes62.5kgimes(12)2=4500J

Answer
The speed of the sled at the bottom of the slide.
The friction between the sled, rider, and the ground, which can be influenced by air resistance and the surface type.
