Part one ) A dragster and driver together have mass
926.8 kg . The dragster, starting from rest,
attains a speed of 26.7 m/s in 0.58 s.
Find the average acceleration of the dragster during this time interval.
part two) What is the size of the average force on the
dragster during this time interval?
part three) Assume the driver has a mass of 70.9 kg .
