Please explain the answer for part c, given the answers for the previous parts of the problem:

A race car is capable of going 44.7 m/s in 0.8 s. The distance of the race is 304.8 m.

A) estimate how fast it takes the car to finish the race

a=tV=0.844.7=55.9m/s2

X=21a(t)2

304.8=21(55.9)(t)2

t2=3.3s

B) estimate it's max top speed

V=(a)t

=(55.9)(3.3)

V=184.5m/s

C) Although it is possible for a car to reach 44.7 m/s in 0.8 s, the world record is 150.2 m/s in 3.662 s. Compare these values to the estimates above. Do the estimates above agree or disagree? If they don't agree why not? Were any estimates used in the calculations above? Are the calculated estimates significant or insignificant compared to the actual values?
