An airboat of the type used in swampy and marshy areas is shown in Fig. 6.29. Explain the principle of its propulsion. Using the concept of conservation of linear momentum, determine what would happen to the boat if a sail were installed behind the fan.
Answer to relevant QuestionsIf a 60-kg woman is riding in a car traveling at 90 km/h, what is her linear momentum relative to (a) The ground and (b) The car? A 2.0-kg mud ball drops from rest at a height of 15 m. If the impact between the ball and the ground lasts 0.50 s, what is the average net force exerted by the ball on the ground? An automobile with a linear momentum of 3.0 x 104 kg ∙ m/s is brought to a stop in 5.0 s. What is the magnitude of the average braking force? A one-dimensional impulse force acts on a 3.0-kg object as diagrammed in Fig. 6.32. Find (a) The magnitude of the impulse given to the object, (b) The magnitude of the average force, and (c) The final speed if the object ...A baseball player pops a pitch straight up. The ball (mass 200 g) was traveling horizontally at 35.0 m/s just before contact with the bat, and 20.0 m/s just after contact. Determine the direction and magnitude of the impulse ...
