Sled Physics on a Slope

As a sled slides down a snowy hill, gravity pulls it forward while friction between the runners and snow slows it down. The net acceleration is a = g(sinθ − μcosθ), where θ is the slope angle and μ is the coefficient of friction between sled and snow.

From that acceleration, the calculator finds the final speed at the bottom using v = √(2ad) and the time to reach the bottom using t = v/a. Typical friction coefficients for a sled on packed snow are around 0.03–0.1; icy or waxed runners can go lower.

This is a simplified model for general planning and educational purposes — it ignores air resistance, curves, and changes in slope steepness along the way.
