... An object acted on by three forces moves with constant velocity. One force acting on the object is in the positive x direction and has a magnitude of 6.5 N; a second force has a magnitude of 4.4 N and points in the negative y direction. Find the direction and magnitude of the third force acting on t ...

... If one of two objects is stationary, and a second object collides with it elastically, the two objects could either move in the same direction or in opposite directions. If the moving object has more mass, then it will have a lot of momentum. It will have enough to keep on going after the colli ...
