The average speed during that period is 500 meters 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.
In general, the acceleration during that time interval could vary considerably. However, we can calculate the average acceleration during the interval. The change in speed is 20 meters per second - 5 meters per second = 15 meters per second, and this change in speed occurs over a 3 second interval. Thus the average change in speed over this interval is 15 meters per second/ 3 seconds = 5 meters per second per second = 5 meters/second2
320 meters
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 )
between 70 and 90 a second
The average speed during that period is 500 meters per second.
The average speed is one fifth of the distance that she travels from the third to the eighth 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.
Its average speed during that period of 3 hours is 182.27 feet per second. (rounded)
The average speed of a wasp is 2.5 meters per second. The wasp beats its wings an average of 250 times per second.
The average speed is 0.0069 miles per second.
In general, the acceleration during that time interval could vary considerably. However, we can calculate the average acceleration during the interval. The change in speed is 20 meters per second - 5 meters per second = 15 meters per second, and this change in speed occurs over a 3 second interval. Thus the average change in speed over this interval is 15 meters per second/ 3 seconds = 5 meters per second per second = 5 meters/second2
The estimated average speed of ocean currents is about 1 meter per second.
320 meters
To find the average speed, divide the total distance traveled by the total time taken. If a car travels 88 meters in 11 seconds, its average speed would be 8 meters per second.
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 )
