The first crash test has the following experimental conditions: Dummy Mass = 77 kg Initial impact velocity = +56 km/h Final velocity after the impact = 0 km/h Barrier: Concrete Wall NO SEATBELT --> Collision timeframe is 400 milliseconds. Calculate the impulse of the dummy during this collision. Round your answer to two significant figures. Answer: 1193.5 kg m s-1 The second crash test has the following experimental conditions: Dummy Mass = 77 kg Initial Impact Velocity = +56 km/h Final Velocity after Impact = 0 km/h DUMMY IS WEARING A SEATBELT --> Collision Timeframe is 600 milliseconds. Compared to the first collision, this crash-test dummy will experience Compared to the first collision, this crash-test dummy will experience Based on the experimental collision data provided above, create a graph showing force vs. time for each of the collisions. For the purposes of this graphing, treat each collision as starting at time = 0 On this graph show the following: 1) Draw both force vs. time profiles on a SINGLE graph. Make sure that each collision's data is clearly indicated. 2) Clearly label the x and y axes. Include appropriate units. You must scan and upload your graph if you draw it by hand. If you create the graph digitally, upload a screenshot of the graph
