... 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 ...

... How would the previous problem change if the boy threw the ball at an upward angle? In this type of problem yi ≠ 0. Therefore, we must account for the fact that gravity (g) first has to bring the upward velocity to a stop and then change the direction to downward. So the path of the object is a pa ...
