Calculations: 1) Calculate the G-force acting on a NASCAR racecar during a crash, where the initial velocity is 187 mi/hr, and the vehicle is stopped by a retaining wall in 0.35 seconds. The final velocity is 0 mi/hr. (Be sure to convert (mi/hr) to (m/s). There are 1,609 meters in one mile, and there are 3,600 seconds in one hour.) You will be using the formula for acceleration = (final velocity - initial velocity) divided by the time. Then, you take that value and divide by 9.8 to get the value for the G-force. For example, if a car is traveling at 83.6 m/s and is brought to a final velocity of 0 m/s in .25 seconds, the G-force it experiences is G = ((final velocity - initial velocity)/time)/9.8 = ((0 - 83.6)/.25 ) / 9.8 = 34 G. We take the absolute value for G, i.e., the negative becomes positive. 2) A top fuel dragster can reach speeds up to 330 mi/hr. If it is traveling this fast, calculate the G-force it experiences when it is stopped by a retaining wall in 0.35 sec. (Be sure to convert (mi/hr) to (m/s), and show all your work.) Do you think the driver can survive such a crash? Explain why or why not. If not, explain what precautionary measures could be taken to increase the odds of survivalStep by Step Solution
