A 11.0-g bullet is fired into a 230-g block of wood at rest on a horizontal surface. After impact, the block slides 7.40 m before coming to rest. If the coefficient of friction between the block and the surface is 0.370, what is the speed of the bullet before impact?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
