20. A 873-kg (1930 lb) dragster, starting from rest, attains a speed of 26.3 m/s (58.9mph) in 0.59 s.
-----a. Find the average acceleration of the dragster during this time interval.
Starting time: 0
Formula to be used: V=Vo + at converted into A=v-vo/t
-----b. What is the magnitude of the average net force on the dragster during this time?
F net= ma
F net = 38,935.8 N
F net = 39,900N
-----c. Assume that the driver has a mass of 68kg. What horizontal force does the seat exhert on the driver?
Here is where i have a problem..[B/]
I would assume I have to do:
F net=ma using 68kg as my M and 44.6m/s as my A to solve for the force exherted by the seat, which would equal 1,788.4N (Horizontal Force seat exherts) Yet I dont know if thats done correctly.. I would love someone to revise over the work, especially C to see if I did it correctly..
