A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 25.0° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier's mass is 55.0 kg , and the coefficient of kinetic friction between the skis and the snow is 0.120. Find the magnitude of the force that the tow bar exerts on the skier.

A toy boat is being pushed with a force of 40.0 N [W] by its engines in a pond. A strong wind blows from the north, which exerts a force of 30.0 N on the boat. What is the net force acting on the ferry? Question 1 options: a 50.0 N [W 36.9° S] b 70.0 N [W 53.1° S] c 50.0 N [W 53.1° S] d 70.0 N [W 36.9° S]
Two teams of nine members each engage in a tug of war. Each of the first team's members has an average mass of 72 kg and exerts an average force of 1350 N horizontally. Each of the second team's members has an average mass of 77 kg and exerts an average force of 1373 N horizontally. (a) What is the acceleration (in m/s2 in the direction the heavy team is pulling) of the two teams?
An SUV containing 5 passengers has a mass of 3500 kg. It has a driving force of 2500 N directed west on a perfectly horizontal road. The surface of the road exerts a resistive force of 500 N due east. At the same time, a strong wind is blowing a force of 500 N due east in the opposite direction of the car's drive force. Does the car have any acceleration? If yes, then what is the magnitude and direction of the car's acceleration?
