have all of mass 15 kg. Initially at rest, it's kept by the force of continued and to a quarter final velocity of four m per second for how long the force is applied. Change of momentum of the world is called to product of force and time, so time will be changing momentum upon applied force. Final momentum minus initial momentum upon force Finding momentum, I'm into final diversity initially zero no substitute the value masses 15 His speed is four upon force that is continue to do so. It will be a point of 12 seconds, so answer you will get that is to be correct.
