WebApr 21, 2024 · We're going to assume that the block is on earth, we're assuming that it's stationary. Well, if it's on earth, the block has some weight. You have the force of gravity acting on the block. And so let me draw that in my free body diagram. So you're gonna have a … 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.
