1. The problem statement, all variables and given/known data 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. My solution: Given variables: M=873kg Vo=0 Starting time: 0 V=26.3m/s T=0.59 Formula to be used: V=Vo + at converted into A=v-vo/t It equals: a= 26.3/0.59=44.6m/s^2 -----b. What is the magnitude of the average net force on the dragster during this time? My solution: Given variables: m=873 kg a=44.6m/s^2 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..
