Runner has an initial velocity of 4 meters per second After 20 seconds the runner's velocity is 6 meters per second Which is the runner's acceleration?
Magnitude of average acceleration = (change of speed) divided by (time for the change)Average 'A' = (6 - 4) / 20 = 2/20 = 0.1 meter per second2-- That's the average over the 20 seconds. We don't know anything about thevalue of the acceleration at any particular instant during the 20 seconds.-- We're working entirely with scalars ... speed, not velocity, and magnitude ofacceleration ... since we don't know anything about the runner's direction atany time during the whole event.
What is the average speed of the runner in miles per hour over the 100 M run?
Depends on the time, average speed = distance / time Usain bolts record time is 9.58 seconds, giving an average speed of: 100 / 9.58 = 10.438 metres per second ( 23.349 mph ) > His maximum speed during the run however, was recorded at 12.22 metres per second ( 27.335 mph )
How far will you travel in 30 seconds accelerating from rest at 1 meter per second per second?
-- Your speed after 30 seconds will be 30 meters per second.-- Since your acceleration is constant, your average speed during the 30 secondsis the average of your initial and final speed . . . 15 meters per second.-- The distance you cover is your average speed for 30 seconds = 15 x 30 = 450 meters.
If a man runs 200 meters in 25 seconds what is average speed?
Average speed = 200 meters per 25 seconds It can also be written as 8 meters per second
If you ran 100 feet in 10 seconds what was your speed?
100 feet in 10 seconds gives an average speed of 10 feet per second.

9 hours
This runner completed a 100 meter race with a time of 13.75 seconds. what was her average speed?
Divide the 100 by 13.75 to find the metres per second speed. 100 ÷ 13.75 = 7.27 metres per second.
