A 873-kg (1930-lb) dragster, starting from rest, attains a speed of 26.3 m\s^2 (58.9 mph) in 0.59 seconds.

Question

I need need with the following problems.

a. find the average acceleration of the dragster during this time interval.

b. what is the magnitude of the average net force on the dragster during this time?

c. assume that the driver has a mass of 68kg. What horizontal forces does the seat exert on the driver?

Especially the last part.

Answer 1

I'd say:
a. (26.3 -0)/(0.59-0) = 44.576 (45 with Sig. Digits)
b. & c. we haven't gotten that far.. Sorry
