if you exert a horizontal force of 200N to slide a crate across a factory floor how much friction is exerted by the floor on the crate? Is the force of friction equal and oppositely directed to your 200-N push? If the force of friction isn't the reaction force to your push, what is?

For the crate to move with a constant velocity, the net external force on it must be zero. Therefore, if I exert 200 N , the force of friction should also be 200 N so that there is no unbalanced force. The force of friction is exerted by the floor on the crate.

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?
