Objective: In this lab/simulation we will look at the power of simulations to validate calculations and/or the needs to often perform estimates, in these cases a simulation is given some initial conditions. In physics, as well as other sciences and engineering we often develop simulations to solve problems that do not readily have closed form mathematical solutions. This us allows one to simulate the response of designs of instruments and mechanisms to external forces and stimuli such as vibration, shock, thermal changes, movement of objects through various medium (i.e. drag), etc. For example, the drag, a car experiences when travelling at speed due to air resistance, or the resistance a boat experiences moving through water. Other examples might include the resistance of blood flowing through arteries and veins as a diagnostic for medical conditions. One of the key confidence tests for a simulation is to test the simulations results against known solutions. In addition, to using these known conditions to test the validity of a simulator the simulator is often used to validate calculations, especially those involving complex calculations. In this lab/simulation, we will solve several questions, and then input the results of the calculation to validate the calculated solution. We will also explore using a simulation designed for a particular set of conditions and adapting it for other situations by simply adjusting the initial conditions and/or looking at the results at various time steps while interpreting the result between the time steps.

Figs.As can he seen the simulation correctly veries the calculation giving us condence in both the calculation and the simulation. III. Exercise 1: Determining the time it takes to move x-distance at constant speed. Q1: If a cheetah can run at speeds of 56 mph, how long will a cheetah take to run 325 meters? (1 mile = 1,609 meters] (Give your answer to the nearest ill seconds. And show your work} 1. Convert the cheetah's velocity to meters per second. 2. Calculate the time for the cheetah to travel 325 meters. S 1: Using the blue car to rcpresent the cheetah, run the simulation using the results from your calculation. 1. Record the simulation value for xBlue at the time elapsed you calculated above. xBlue: 2. Calculate the percent error between your simulated value and the 325m distance given in the
