First find the acceleration rate (actually deceleration in this case). Equation is a = (v2- u2)/2s where a = acceleration, v = final velocity, u = initial velocity, s = distance
but remember you must use consistent units, 60 km/hour = 16.67 meters/sec
so v = 0, u = 16.67
so a = -16.672/2 x 30 = - 4.63 meters/sec2 , time = (v - u)/a = 16.67/4.63 = 3.60 secs.
120 meters per 20 seconds
600/30 = 20 meters per second.

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.
Sound is a transverse wave made by particles banging into one another. (thus sound cannot travel in a vacuum) In air (a gas), the particles are a long way apart so it takes longer for them to collide with one another to carry the sound. In a solid, say a bar of metal, all the particles are jammed really close together, so if you bang one end of the bar, the wave will travel quickly down the length of the bar. Sound travels at around 330m/s in air, and how fast it goes in solids depends on the properties of the solid, but I think for most metals it is very roughly around 600m/s Hope this helps.
600m:5km = 600m:5000m = 600/5000 = 3/25
Use the formula distance = speed x time. Solving for time: time = distance / speed.600/10 = 60. It would the hawk 60 seconds (1 minute) to travel 600m.
you obviously run 600m

The Inspiron 600m is manufactured by the Dell computer company. Dell released the Inspiron 600m during the middle of 2003. The Inspiron 600m is designed to travel with you since it is so thin and light.

fraction = 600m/1000m or 6/10 or 3/5 note: 1 km = 1000 m
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.
