A dragster and driver together have mass
902.2 kg . The dragster, starting from rest,
attains a speed of 25.1 m/s in 0.55 s .
Find the average acceleration of the drag-
ster during this time interval.
Answer in units of m/s2

011 (part 2 of 3) 10.0 points
What is the size of the average force on the
dragster during this time interval?
Answer in units of N

012 (part 3 of 3) 10.0 points
Assume the driver has a mass of 73.5 kg .
What horizontal force does the seat exert
on the driver?
Answer in units of N

Explanation / Answer

1)average acc= (v-u)/t=45.63 m/s2 2)average force=m*a=41173.127 newton 3)force exerted by seat = md*a=3354.27 newton
