Exercises with Vectors-II Name [1] Suppose you have two vectors, a and b, that have the same length, so that lal-lb but they point in different directions. Denote the angle between them by . Show that tan(0/2) la-bMa+b Hint: Compute the right-hand side using the fact that lal-bl, and the trig identities 1-cos θ-2sin'(9/2) and 1+cos9-2cos(θ/2) 12] Vectors in 3-dimensions are often parameterized in terms of their length and two angles, as shown in the figure (think of a...
2. Linear dependence of vectors: If we want to describe any vector in three dimensions, we need a basis of three vectors, and we usually choose i,j. k, the unit vectors in the r, y, z directions. We could equally well have chosen for example a = i+5, b = i-j and c = i+2] _ k. Then the vector v = 41+2] _ k would be expressed as v = 3a + )b-c a, b, c form a suitable...
A projectile P of mass m is fired from a point 0 with initial speed v0 at launch angle φ0 above a horizontal firing range. In addition to gravity, P is subject to the aerodynamic drag force by the surrounding air modeled as a quadratic function of speed where v is the velocity of P and k is a positive pa- rameter. 0 0 We are interested in studying the effect of Faero on various aspects of projectile motion. Since...
Problem 1. (15 points) Recall, the Eulerian angles that we defined in class as shown below. The axes (î, þ, â) are fixed in body frame B and the axes (Î, Ê, Â) are fixed in the inertial reference frame F. The orientation of B with respect to mathF is represented through the angles (0, 0, 4) using a sequence about intermediate z, intermediate y and intermediate z-axis again to obtain body-fixed frame B in the final configuration, from the...

Mail A A wrench 40 cm long lies along the positive y-axls and grips a bolt at the origin. A force is applied in the direction (0, 4,-3) at the end of the wrench. Find the magnitude of the force needed to supply 90 N·m of torque to the bolt Stop 1 The magnitude of the torque τ developed by applying a force F at a point with position vector r at an angle θ to r is given by...

1. This quasi-"walkthrough" problem is great practice in cross-products, vectors, and integration. Consider the current loop shown in Figure 2, with B _Bx, and the loop lying in the x - z plane of the page (y points into the page). We wish to find the net torque on this current loop. we'll do this by integrating in θ, the angle shown (a) We'll start with a little segment dl at point p as shown in the figure. What is...
