1.Dave and Alex push on opposite ends of a car that has a mass of 875 kg. Dave pushes the car to the right with a force of 250 N, and Alex pushes to the left with a force of 315 N. Assume there is no friction. a. Draw a free-body diagram showing all the forces acting on the car. (2 points) 2.A water-skier is pulled behind a boat by a rope that is at an angle of 13 and has a tension of 490 N. The water-skier has a mass of 49 kg. a. Draw a free-body diagram showing the forces acting on the skier. (She is being pulled to the right.) (2 points) 3. Your dog sleeps on the floor. He has a mass of 14 kg. The coefficient of static friction between him and the floor is 0.3, and the coefficient of kinetic friction is 0.25.e. Later, you are sliding your dog across the floor at a speed of 2 m/s. What is the force of kinetic friction acting on your dog? (1 point) 4.Blaine steps onto a ski slope with an angle of 25. There is a coefficient of kinetic friction of 0.15 between him and the ground. He has a mass of 65 kg. a. Draw the free-body diagram showing the forces acting on Blaine. (1 point)
