at a drag race a jet car travels 1/4 miles in 5.2 seconds. what is the final speed of the car and its acceleration?

Answer 1

average speed = .25 mi / 5.2 s

so top speed = 2 * average speed if a is constant
so
Vf = .5 mi /5.2 s
if you want that in mi/h multiply by 3600 s/h
so
Vf = 346 miles/hour

Vf = a t
.5/5.2 = a (5.2)
a = .01849 miles/s^2
makes more sense if in feet/s^2
multiply by 5280 feet/mile
a = 97.6 feet/second^2
