8.27 The following data is obtained for the velocity of a vehicle during a crash test.: 40 |:| 10 t (ms) v (mph) 0 30 10 29.5 20 28 30 23 50 5 60 2 70 0.5 80 0 If the vehicle weight is 2,400 lb, determine the instantaneous force Facting on the vehicle during the crash. The force can be calculated by F = may, and the mass of the car m is 2400/32.2 slug. dt Note that 1 ms = 10-3 s and 1 mile = 5,280 ft. (a) Solve by using the user-defined function First Deriv that was written in Problem 8.17. (b) Solve by the using MATLAB built-in function diff. 8.27 The following data is obtained for the velocity of a vehicle during a crash test.: 40 |:| 10 t (ms) v (mph) 0 30 10 29.5 20 28 30 23 50 5 60 2 70 0.5 80 0 If the vehicle weight is 2,400 lb, determine the instantaneous force Facting on the vehicle during the crash.
