1. The problem statement, all variables and given/known data A 10.0 kg box is acted on by a constant force of 50.0 N. If it passes a first timer with a speed of 2.0 m/s and then travels 150 cm to a second timer, what would its speed be as it passes the second timer? 2. Relevant equations I know usually to find out the speed of an object it is usually distance over time. I know the distance being 150 cm However as there is no time i've come to a complete stand still 3. The attempt at a solution Stuck at the beginning, if someone would be kind enough to point me in the right direction please.
