33.33 meters per second.
30,000 metres or 30km
120 km/hr (1000 meters/1 km)(1 hr/60 minutes) = 2000 meters per minute ---------------------------------
Acceleration = (change in speed) / (time for the change)= (10 - 25) / 240 = -15/240 = -0.0625 meter/sec2The acceleration is negative, which is a description of slowing down.
Completely ignore the first train.The second train passes the pole in 8sec.In this 8 seconds the train drove 120 meters.So the train has a speed of 15meters per second (120/8=15).Answer: 15 (meters / second) = 54 km/h
a high speed train travels south for 2.00 h for a distance of 454km. what is its average velocity?
The average speed of the train is 41 meters per second. This is calculated by dividing the distance traveled by the time taken: 861 meters / 21 seconds = 41 meters per second.
Average acceleration over an interval of time = (final speed - initial speed) / (time for the change)= [ (0 - 30) / 1 ] (meters / second-minute) = [ (0 - 30) / (60) ] (meters / second-second) =-0.5 meter / sec2
The people on the train are watching you go by at 20mps. It's all relative.
At 200 mph, the train is moving at 293.3 feet per second.
120 km per hour = 33.33 meters per second.
(120 km/h) x (1000m/ 1km) x (1hour/ 3600seconds) = 33.3 m/s
454 km
33.3km/sec
33,055m or 33.055Km
30,000 metres or 30km
40 x 10 x 6 = 2400
A normal train usually travels at a speed of 100mph.
