A 880-kg (1945 lb) dragster, starting from rest, attains a speed of 27.3 m/s (61.0 mph) in 0.60 s.
(a) Find the average acceleration of the dragster during this time interval?
(b) What is the size of the average force on the dragster during this time interval?
(c) Assume the driver has a mass of 66 kg. What horizontal force does the seat exert on the driver?
