15 mph = 22 feet per second
Walking at a meter per second would take 900 seconds (15 minutes); at a faster walk, 1.5 meters per second, about 600 seconds ( 10 minutes).
6.66 meters per second.
Kilometers is a distance 15 mph is a speed but 15 mph = 24.14 kilometers per hour The formula to convert miles to km15 mi* 1.609344 km 1 mi = 24.14016 km
Acceleration = change in speed per unit of time = (15-0)/10 = 1.5 metres/sec2
15 mph = 22 feet per second
The speed of the plane after 10 seconds of acceleration at 15 m/sĀ² would be 150 meters per second. This is calculated by multiplying the acceleration (15 m/sĀ²) by the time (10 seconds).
1 km per second is defined as equal to 1000 meters per second. Therefore, a speed of 15 meters per second is 15/1000 km per second or 0.015 km per second.
38 mph = 5511/15 feet per second(55.733...)
22
85 Miles per Hour = 124.67 Feet per Second
To convert 22 feet per second to mph, multiply by 0.681818. So 22 feet per second is approximately 15 mph.
22 feet 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
15 metres per 2 seconds = 7.5 metres per second.
Multiply by 1.47: 15 x 1.47 = 22.05 feet per second
1.667 metres per second squared
