2. (4) An airplane is trimmed straight and level at a true airspeed of 50 m/s...
Consider an airplane whose takeoff speed is 225 km/h and that takes 16 s to take off at sea level. For an airport at an elevation of 1600 m (such as Denver), determine the following: a. The takeoff speed b. The takeoff time c. The additional runway length required for this airplane
Pictured below is a model for a train that is traveling at the steady speed of 50 m/s through standard air at sea level. The cross section of the train will be modeled as a semicircle so that the train itself is half of a circular cylinder. Neglect the effects of any airflow beneath the train. The engine car drives the train with a propulsive thrust, and there is a coupling connecting the engine car to the passenger car. Assume...
Problem A car travels at a constant speed of 29.5 mi/h (13.2 m/s) on a level circular turn of radius 46.0 m, as shown in the bird's-eye view in Figure 7.13a. What minimum coefficient of static friction, Aus, between the tires and the roadway will allow the car to make the circular turn without sliding? Strategy In the car's free-body diagram (Fig. 7.13b) the normal direction is vertical and the tangential direction is into the page (step 2). Use Newton's...
2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses 2.20 gallons of gasoline. Only 30% of the gasoline goes into useful work by the force that keeps the car moving at constant speed despite friction. (The energy content of gasoline is 1.3 ✕ 108 J per gallon.) (a) What is the force exerted to keep the car moving at constant speed? N (b) If the required force is directly proportional to speed, how many...
Please solve using algebra only 2.) A proton moving initially at speed v-200 m/s enters a region of constant magnetic fickd B 0.4T pointing out of the page as shown in the figure. a) Describe and draw in the figure its subsequent path as it moves i b) Co figure its direction at various points along its path. e) Where would you place a uniformly charged plate in this region so that the proton will maintain a straight path with...
Procedure: Materials: 1. apparatus 2. 2 pieces of metal track 3. plastic or metal ball 4. timer 5. meter stick 6. micrometer 7. 2 photogates Assemble your ramp as shown in Figure (1) in the next page. Then set up photogates in location 2 and 3. Measure the diameter (in m) of the metal balls (you will need it for speed calculations). Then, measure the weight (mass) of the ball (in kg). To have a better measurement of the time,...
