A block of ice of mass 3.90 kg is placed against a horizontal spring that has force constant k = 230 N/m and is compressed a distance 2.40×10−2 m . The spring is released and accelerates the block along a horizontal surface. You can ignore friction and the mass of the spring.

A. Calculate the work done on the block by the spring during the motion of the block from its initial position to where the spring has returned to its uncompressed length.

B. What is the speed of the block after it leaves the spring?

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.
