To totally cross the bridge the train must travel (850m + 150m) 1 km.
1 km in 100 seconds is 10 m/s
roughly 20 mph, so the answer is yes, with ease.
30 seconds When the front of the train is at the start of the bridge, the back is still 50 metres away. When the back of the train crosses the bridge then the time stops. So 50 + 250 = 300 300 / 10 = 30
That depends on the length of the bridge.
Distance of fall in T seconds = 1/2 g T2Distance of fall in 2 seconds = (1/2) (9.8) (2)2 = (4.9 x 4) = 19.6 metersHeight of this particular ball after 2 seconds = (70 - 19.6) = 50.4 meters
To beat level 18 on IQ ball, you need to wait until the tractor crosses the bridge. ( to limit the weight) Then grab a hold one side of the bridge and it will collapse. ( If this action does not happen the first time, try multiple times and the bridge will eventually break.) Try not to get caught under the bridge once it collapses, because you will have a really hard time getting to the target.
Velocity final = vi + at = 49 m/s displacement = vi * t + ½2at² = 122.5 m vi = 0 a ≈ 9.8 t = 5

200m. Here's the work:The speed of the train in meters per second is:(36km/hr)(1000m/km) / (3600s/hr) = 10 m/sIf it takes 80 seconds to cross, then the distance traveled in 80s at 10m/s is:(10m/s)(80s) = 800mNow, imagine this:The front end of the train travels 800 meters from the time it reaches the bridge until the back end is clear of the bridge. This means that the length of the train equals the distance traveled minus the length of the bridge.So:800m - 600m = 200mThe train is 200m long.
London Bridge.
tasmania bridge
A bridge's span is the length that crosses the gap.
The first people were Native Americans who crosses the land-bridge from Asia to North America. The first outsiders were Europeans who traveled the Atlantic by ship.
the something that crosses the river is called a bridge.
A bridge.
The Mid-Bay Bridge.
The Golden Gate Bridge crosses the Golden Gate, which is the strait connecting the San Francisco Bay to the Pacific Ocean.
Tower Bridge.
That bridge is called The Fiorth Road Bridge.
