Tube up a Hill

At a ski resort, a powered pulley moves a \({{params.W}} lb\) tube up a snowy hill (\(\theta=\)17 \(^\circ\)) at a constant speed of \({{params.v}}ft/s\).

Part 1

If the power output is \({{params.P}}hp\), compute the coefficient of kinetic friction between the hill and tube.

Answer Section

Please enter in a numeric value.

Part 2

If the power is increased to \({{params.P2}}hp\), what is the new acceleration?

Answer Section

Please enter in a numeric value in \(ft/s^2\).
