How long will a train of 50 m will take to pass over a bridge of 250 m at a speed of 10ms?
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
How many times would one have to journey back and forth over the bridge to have traveled one mile?
That depends on the length of the bridge.
David drops a ball from a bridge at an initial height of 70 meters what is the height of the ball to the nearest tenth of a meter exactly 2 seconds after he releases the ball?
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
How to beat level 18 on IQ BALL?
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.
A marble dropped from a bridge strikes the water in 5 seconds. What is the speed with which it strikes and the height of the bridge?
Velocity final = vi + at = 49 m/s displacement = vi * t + ½2at² = 122.5 m vi = 0 a ≈ 9.8 t = 5
A 130m long train crosses a bridge in 30 seconds at 45 kmph The length of the bridge is?
245m
A train of certain length travelling with a uniform speed of 36kmhr crosses a bridge of 600m in 80 secfind the length of the train?
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.
