Question
the following data is obtained for the velocity of a vehicle during a crash test:
t(ms) v(mph)
0 30
10 29.5
20 28
30 23
40 10
50 5
60 2
70 0.5
80 0
if the vehicle's weight is 2,400 lb, approximate the force f in lb acting on the vehicle 40ms after the crash. the force can be calculated by F=m(dv/dt) , and the mass of the car m is 2400/32.2 slug. note that 1 ms=10^-3 s and 1 mile = 5,280 ft. convert t to secons and mph to fps. use 1st order forward, backward, and centered difference and apply Richardson's approximation. use h1=0.02 and h2-0.01s.
