- Problem 1: A block having a mass of m= 14 kg is suspended via two cables as shown in the figure. The angles shown in the figure are as follows: a = 12° and B= 28°. Cable l Cable 2- marrow_forwardI have a question for the square root of units. So I have the formula 2pi√m/k And m=50g and k=32,700 dynes/cm. (dynes is g x cm/sec2) So when I plug everything in and cancel units out im left with √654sec2 My question is does the square root cancel out with sec2 individually so i'll still have to square root 654 or does the square root cancel out with the whole thing and im left with 654 without having to square root it. Therefore leading to 2pi(654sec). Or would it be 2pi(25.6sec)arrow_forwardYour formula is correct, but number is not. You forgot to multiply t=24s in step 1, at the line .... = 999v. So follow your formula, the answer will be 77.34m. I rated (y).arrow_forward
- Step 1 Rewrite the original integral Therefore, let du a² + u² (²) dt as + 16 = arctan(y) to Step 2 Use the following integration formula for the inverse trigonometric functions. 1.20 t (27²2² +42 (2) ot = (- t 1 + X X 4 2 (2) dt arctant arctan tan()+c 4 ✓)) + Carrow_forwardOn a plane flat surface with "up" given as +y and "right" given as +x, we add two vectors. One of them has components (4, 4). Their sum is (3,6). What is the unknown second vector and what is its angle to the x-axis? Hint: The angle is the one that has a tangent that is the ratio of its y to its x component, or a sine that is the y component divided by its length. The second vector is (-1,-2). It is about 63° down from -x. The second vector is (7,10). It is about 55° up from +x. The second vector is (1,-2). It is about 63° down from +x. The second vector is (-1,2). It is about 63° up from -x.arrow_forwardLet u = 8i + 2j and v = 8i − j. (a) Find the angle between u and v. (Round your answer to one decimal place.) (b) Find the component of u along v. (c) Find projvu.arrow_forward
- Determine the value/s of x using complex number conversions and operations. Express answers in indicated form (i.e. if the given complex number is in rectangular form, the answer should be in rectangular form). x = (e^(-3+j4)) – (e^(1+j2)) Answer should be in exponential formarrow_forwardConsider the following matrices: 2. C=4 0. 1 /1 3 B = 2 0 1 1 0 A = 0. 6. 1 8. 9. 1. Add the matrices that can be added. What is their sum? 2. What is 5AB equal to? 3. Suppose there is another matrix D, what should be its dimensions so that ABD can be evaluated?arrow_forwardCase a<r<b : your dA is πr^2 but when you rearrange for E your denominator is 2πε0r^2 where did the 2 come from ? Thanks :)arrow_forward
- I am confused on how to start this problem. I know I need to use the y(x,t)=Asin(kx+wt+phi) formula, but do I need to take the derivative of that once I enter in all the variables? I am referenceing the problem 14 in the pic I attached. Thanks!arrow_forwardJ= , (r2 + 2)V () dr. find the value of J. Note that the divergence relation in spherical coordinates is given as follows V.v = r ar (sin@ ve) + r sin e ap r sin e aearrow_forward(1) Show that planes perpendicular to the x-axis have equations of the form r = a sec 0 in cylindrical coordinates. (2) Show that planes perpendicular to the y-axis have equations of the form r =b csc 0 in cylindrical coordinates. (3) Find an equation of the form r = f(0) in cylindrical coordinates for the plane ax + by= c, where c+ 0.arrow_forward
