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.

Q3: Usain Bolt, the world's fastest human, can run the 200m dash in 19.19 seconds which equates to an average speed of 10.42 m/s (23.32 mph). Assuming Fred can run the 200 meter dash in a very respectable time of 35 seconds flat, how much of a head start would Usain Bolt have to give Fred in order for them to both cross the finish line at the same time. 1.

Fill in Usain Bolt's average velocity in the 200m dash in vBlue. Usain's starting position and acceleration are both zero. 2. Fill in your calculated values for Fred's average velocity and the required head start in vRed and xRed respectively. Fred's acceleration is zero. 3. Run the simulation for 35 seconds. 4. Do Fred and Usain Bolt cross the 200 m point at the same time within the measurement and rounding errors? 5. Assuming they can both keep up the same speed, how much further ahead is Usain Bolt after 28 seconds
