A sled is sliding down a 2 m high slide. What path will the sled go on a horizontal section if the coefficient of friction on it is 0.06? Slide friction neglected
Task data: h (slide height) = 2 m; μ (coefficient of friction in the horizontal section) = 0.06.
To calculate the path of the sled on a horizontal section, we apply the law of conservation of energy: ΔEp = ΔEk = Atr; m * g * h = Ftr * S = μ * m * g * S, whence S = m * g * h / (μ * m * g) = h / μ.
Let’s perform the calculation: S = 2 / 0.06 = 33.3 m.
Answer: On the horizontal section, the sledges will pass a path of 33.3 m.
