Determine the acceleration of the block when pushed with a … WebWhen two rough surfaces are in contact, the actual contact area is a tiny fraction of the total area because only high spots touch. When a greater normal force is exerted, the actual …
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.
