In a sitution the constant force by a rough

WebQuestion: (1) A force F is required to push a crate along a rough horizontal floor at a constant speed V with friction present. What force is needed to push this crate along the same floor a at constant speed 3V if friction is the same as before? A constant force 3F is needed. A force that gradually increases from F to 3F is needed. Webthe friction force will either push the object up if it slides down or it will push the object down as it slides up. mg N P f s mg N P f s For the object to be stationary in the sitution at left, 2nd Law requires: mg+ f s = psin and N= pcos with f s = sN mg+ sNcos = psin p(sin s cos ) = mg p = mg sin s cos p = 1:75 9:81 sin50 0:260cos50 P max ...

WebIf given a description of a physical situation, begin by using your understanding of the force types to identify which forces are present. Then determine the direction in which each force is acting. Finally, draw a box and add arrows for each existing force in the appropriate direction; label each force arrow according to its type. WebAug 8, 2024 · When an object is moving with constant velocity, it means that there is 0 acceleration and hence no force and no work done. But, this is only partly true. Generally an object, when it moves with constant velocity, is overcoming some friction and some force is being applied to balance it.
