An 865 kg (1912 lb) dragster, starting from rest, attains a speed of 26.7 m/s (59.8 mph) in 0.59 s.
(a) Find the average acceleration of the dragster during this time interval.
m/s2
(b) What is the magnitude of the average net force on the dragster during this time?
N
(c) Assume that the driver has a mass of 68 kg. What horizontal force does the seat exert on the driver?
N
