Top fuel dragsters are some of the fastest accelerating vehicles on earth. After finishing their quarter mile run, a parachute deploys and they come to a stop within a few seconds. As a result of the extreme deceleration, drivers have been known to detach their retinas. Just thought that might be interesting. For the purposes of this problem, assume that the dragster crosses the finish line at a top speed of 333 mph and it has a weight of 2225 lbs.
a) if the acceleration is constant over the entire run, what is its magnitude? how long does it take the driver to complete the course?
b)assume that, after the dragster crosses the finish line, the engine cuts off and a parachute opens generating a drag force, Fd= AVx. draw a free body diagram of the dragster.
c)if it takes 17.5 seconds for the dragster to reach 1/10 of its top speed, what is the value of the constant, A
d) what is the peak magnitude of the acceleration experienced by the driver during the race?
