Question

This lecture involves solving the following 2-D kinematic problem A cannon with a muzzle speed of 1,000 m/s is used to start an avalanche on a mountain slope. The target is 3,000 m from the cannon horizontally and 800 m above the cannon. Determine the angle, above the horizontal, that the cannon should be fired. In the space provided below, write out the mathematical expression for the vertical displacement (y) based on the horizontal displacement (x), the angle (0), and the acceleration in the vertical direction (ay) provided in the pre-lab lecture. Provide the cell location for the value used for the independent variables Cell location ofx- Cell location of v Cell location of ay Cell location of θ = desen onfr fiom abvedetermine the Escel oquatio necesaryto Provide the two acceptable angles (in degrees) that were determined using Solver in Excel. Provide the two acceptable angles (in degrees) that were determined using Solver in Excel. Step 2: On a separate Excèl worksheet, solve the following problem from scratch using the approach outlined in the previous steps. Don't not waste time trying to reduce this expression or rearranging this equation for the variable of interest (T). The acceleration of an object undergoing simple harmonic motion can be described by the equation 2π 2π where a(t) is the acceleration of the object over time (in m/s), A is the amplitude of motion (in m), T is the period of oscillation (in s), and t is the time (in s). Given that the amplitude of the object is 2.34 m and the acceleration is 1.89 m/s2 after 3.45 s has passed, determine the period of oscillation. Step 3: Determine six correct periods and submit the complete spreadsheet with six correct answers (expressed to six decimal places) included to the Blackboard drop box.
