Tube up a Hill#

At a ski resort, a powered pulley moves a \({{params_W}} lb\) tube up a snowy hill (\(\theta=\)27 \(^\circ\)) 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 \(ft/s^2\).
