If it is going from rest, it's speed after 5 seconds is 12.5 metres per second
395000 meters/9000 seconds is 43.889 meters/second
That's easy, if the car is initially traveling at 25 meters per second and gradually accelerates 3 meters per second for 6 seconds then the car is traveling at 43 meters per second.
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.
At 25 meters per second a car will travel 100 meters in 4 seconds and 1000 meters in 40 seconds.
it is 10 meters per second + 7 seconds * e^2 / 3 + 22 meters * 5 = approximately 137.2 kilometers per hour. Because the car isn't traveling in a circular motion and you need meters per second, you need to do the following: 137.2 / (2 * pi * 3.6) = 32.104 meters per second
Just divide the distance by the time. The answer, of course, is in meters/second (meters per second). If you want to convert this to kilometers per hour, multiply the number of meters/second by 3.6.
you doing homework???
The sprinter's acceleration is 2 meters per second squared.
Speed=Distance/ Time For example: You go 40 meters in 10 seconds. 40/10= 4. So you would be traveling at 4 meters per second.
It is accelerating at 1.2m/s 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 its wavelength is 50 meters with a period of 6.5 seconds it means it is traveling at 50 meters every 6.5 seconds or 50/6.5 = 7.7 meters/sec.
