1) A dragster and driver together have mass
921.9 kg . The dragster, starting from rest,
attains a speed of 26.7 m/s in 0.56 s .
Find the average acceleration of the drag-
ster during this time interval.
Answer in units of m/s2

2) 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

3) 012 (part 3 of 3) 10.0 points
Assume the driver has a mass of 77.2 kg .
What horizontal force does the seat exert
on the driver?
Answer in units of N

Explanation / Answer

1) a = v/t = 26.7/.56 =47.67 2) F = Ma = 921.9*47.67 = 43954.6 3) F'=77.2*47.67 =3680
