Determine the angle between u and v The angle between u and v is (Type an integer or a decimal rounded to the nearest hundredth as needed.) The wind is blowing at a speed of 31 mph in a direction of S 48 W. Express the velocity of the wind as a vector in terms of i and j The vector for the wind velocity in terms of i and j is v-(Di(i (Round to two decimal places as needed.)
The magnitude of a velocity vector is called speed. Suppose that a wind is blowing from the direction N45°W at a speed of 50 km/h. (This means that the direction from which the wind blows is 45° west of the northerly direction.) A pilot is steering a plane in the direction N60°E at an airspeed (speed in still air) of 100 km/h. The true course, or track, of the plane is the direction of the resultant of the velocity vectors...

(This means that the direction from which the wind blows is 45° west of the northerly direction.) A pilot is steering a plane in the direction N60°E at an airspeed (speed in still air) of 150 km/h. The true course, or track, of the plane is the direction of the resultant of the velocity vectors...
need help with fluid mechanics problem Name: 4. (15 pts) Wind blowing past a flag cuses it to"ap in the breeze. The flapping frequency is assumed to be a function of the wind speed V, air density p gravitational acceleration g, length of the flag I, and the area density" pa (which has dimensions M/L2) of the flag material Using the Buckingham Pi theorem with V, p, and Las your repeating variables, determine the relevant dimensionless groups. Nate. You must...
A ball is thrown straight up at speed in the presence of gravity. (a) Ignoring air resistance at first, what is the maximum height the ball reaches? (b) Now include Newtonian (quadratic) air resistance, with drag coefficient c. Letting the direction point upwards, write down the equation of motion (be careful with the signs). (c) Solve the equation of motion to find v(t)(= (t)). Remember to check that v(0) = . (d) Without integrating anything yet, calculate the time at...
I need the answers to these ten questions. I have attached them below. Please answer them all. Many many thanks in advance!! When a torch is brought 2 times closer, how many times brighter will it appear? O 16 A diffraction grating that contains 650472 lines/m is illuminated by monochromatic light (λ-632.8 nm) from a helium-neon laser directed perpendicular to the surface of the grating. What is the angle for the second order maxima to occur? 24° O 45 48...
Need help working out this entire question. Question # V The set of eight random numbers shown depicts measured wind-speeds v (in mph) of a hurricane in eight directions at a location. The associated probability values p(v) of the RV are also listed.

need help answering 3 and 4. I posted the answers for 1 and 2 right below this problem. Below that is an example problem showing how i need number 3 and 4 formatted. the actual problem i need solved is different from the example problem in that the left side has a wall, so there is a moment, and there is compression instead of tension. 0005n app > VopP = 10,000 lb L, .
