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 6.2N ; a second force has a magnitude of 4.7N and points in the negative y direction.
Find the magnitude of the third force acting on the object.Find the direction of the third force acting on the object.
Two packages at UPS start sliding down the ramp. Package A has a mass of 6.50 and a coefficient of kinetic friction of 0.19. Package B has a mass of 9.50 and the coefficient of kinetic friction of 0.140. How long does it take package A to reach th..
At one instant a bicyclist is 49.0 m due east of a park's flagpole, going due south with a speed of 14m/s. Then 35.0 s later, the cyclist is 49.0 m due north of the flagpole, going due east with a speed of 14m/s.
