This paper describes a follow up project that provides the first-year engineering students with hands-on experiences while learning the applications of physics. In Fall 2021, this team project used 6” or 8” long ash blocks with 2.5″x 2.5″ cross sections. Different blocks were used in Spring 2021. These blocks (or vehicles or busses) were propelled horizontally with various grades of model rocket engines. The vehicles have wheels inserted on axles. Each vehicle was hooked on to and guided by two 1/16″ diameter steel cables stretched along a 32-foot runway. Each vehicle was constructed starting with a 26″ long ash block. A special jig was designed to line up axle holes on both sides. Two or three 2″ deep engine compartments, (45/64)″ and/or (61/64)″ in diameter, were drilled on the back of each block. An altimeter that acts as an accelerometer was fitted on top of each vehicle. Vehicles were painted and assembled by the students. In Fall 2021, fully loaded vehicle masses (including the masses of engines) ranged from 0.4 kg to 1.1 kg. This team project is centered on derivation of the speed and distance curves by numerically integrating the acceleration data downloaded after each run with the goal of calculating impact speed and energy. The project includes applications of MS Excel programming to accomplish the goals. Most of the students are introduced to MS Excel in this course. The main design goal was the determination of the launch mass and/or the total impulse that allow the vehicle to traverse the entire runway with a decreasing acceleration to achieve a lower impact upon arrival speed. Students learned how to code several sets of dynamics and other physics equations using MS Excel. They were also exposed to the idea of numerical integration. The students were able to apply the concept of integration as they analyzed data. The concept of area under the curve and its importance in engineering was introduced. Each team wrote a technical report that explained the overall project using pictures and graphs to illustrate various parts of the project. In Spring and Fall 2021 semesters, many students felt that they were engaged in an exciting and a worthwhile learning experience that exposed them to concepts in science and engineering that they will be studying in the future. The students’ knowledge gain and engagement surveys were analyzed to assess educational impacts of this project.
