Sorry to waste your time on wot should be a simple question: A boat is travelling at 30 metres per second and begins to decelerate at 0.6 metres per second/per second. How much distance would it cover ( in metres) would it cover before it comes to a compete stop? I have tried solving this with the question v2^2 = v1^2 + 2ad. v1 = The intial velocity which is 30 metres per second v2 = The final velocity which I believe is 0 meters per second; a complete stop. a = The acceleration which is 0.6 metres per second/per second d = Distance covered When I try to solve the equation and isolate the variable "d" I get a rediculous answer. Am I doing something wrong? Is v2 not 0 metres per second? Is this the wrong equation? Do I need to find out other variables such as time to solve this? All help is appreciated.
