Discussion #3 1. Consider the motion of an object that can be treated as a point particle and is traveling counter-clockwise in a circle of radius R. This motion can (and will for the purposes of these discussion activities) be described and analyzed using a Cartesian (x-y) coordinate system with a spatial origin at the center of the particle's circular trajectory (the physical path its motion traces out in space). (a) Draw a diagram of the position...

Part B: Launching a Projectile at an Angle (1) Erase the trajectory from part A (yellow eraser button). (2) Ensure that the initial height (h = 10 m) and initial speed (1 = 15 m s 1) remain equal to the quantities given in part A. (3) Position the projectile launcher so that it launches at an angle of 20°. (4) Fire the launcher (using the red fire button) and record the x-displacement by positioning the center of the target...
1. Which of the following equations are dimensionally correct? a.) V = V1 + ax (10p) b.) y = (2m)cos(kx), where k = 2m-1 (10p) 2. Given the vectors A = 2.001 + 6.00j andB = 3.00i + 2.00j. a.) draw the vector sum C = A + B and the vector differenceD = A - B. (10p) b.) Calculate C and D, first in terms of unit vectors and then in terms of polar coordinates, with angles measured with...
1. (30pt) LC Circuit and Simple Harmonic Oscillator (From $23.12 RLC Series AC Circuits) Let us first consider a point mass m > 0 with a spring k> 0 (see Figure 23.52). This system is sometimes called a simple harmonic oscillator. The equation of motion (EMI) is given by ma= -kr (1) where the acceleration a is given by the second derivative of the coordinate r with respect to time t, namely dr(t) (2) dt de(t) (6) at) (3) dt...
Question 7 is related to the force vs mass graph that is
provided and the first section of the excel sheet. Question 3 has
to do with the force bs acceleration graph and second section of
the excel sheet. The first two files are showing the equations that
are supposed to be used to find these answers. Any help would be
greatly appreciated.
