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.

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.
How is sound made why does it travel faster through solid elements and what is its speed?
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.
What would be the ratio of 600m and 5km?
600m:5km = 600m:5000m = 600/5000 = 3/25
How do you win a 600m running race?

A hawk can travel at 10meters per seconds how long would it take for it to travel 600m?
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.
