30 m/s
Use the kinematic equation:
vf=vi+at,
where:
vf is the final velocity, vi is the initial velocity, a is the rate of acceleration, and t is the time interval.
Known
vi = 0 m/s
a = 6 m/s2 = 6 m/s/s
t = 5 s
Unknown
vf
Solution
Plug in the known values and solve.
#vf = 0 + 6 m/s/s x 5s = 30 m/s
A race car accelerates from rest at a rate of 6m/s^2. How fast will the car be going after 5 seconds?
Answer: 1.2 m/s75 meters
30m/s
30 ms
On average you will be going around 18.75mph
a few things missing: - How fast is the acceleration? - How long does it take to go from 4ms to 20ms?
14.4km/hr or 9miles/hr
160 m
You are running 23.31 miles per hour.
You have averaged 36.5 miles per hour. You are probably going quite a bit faster than that at the end.
100 meters/15.2 seconds 100 meters = 0.0621371192 miles 15.2 seconds = 0.00422222222 hours 100 m/15.2s = 14.7166861 mph average
quarter-mile drag race in under 10 seconds
It is a fairly anaerobic race due to the fast speed you are going at the hole time. I guess you could say the first 200m are aerobic because you are getting into the race, but you are going so fast (if your good enough) to have it be all run without oxygen.
