Snowboarder Sherry of mass m is pulled up a slope at constant velocity v by a tow bar. The force of the tow bar is parallel to the slope, which is inclined at (theta) with respect to the horizontal. The coefficient of kinetic friction between the snowboard and the snow is (mew)k
(A.) find the force that the two bar exerts on Sherry.
(B.) Calculate the force exerted by the two bar on a 46 kg snowboarder being pulled at 3 m/s up a 20 degree slope if the coefficient of kinetic friction is 0.11.
