Which ever changes during a physical change?

Calculate the acceleration if you push with a 20 n horizontal force on a 4 kg block on a horizontal friction-free air table.

A horizontal force of 30 n pulls a block of mass 2.5 kg across a level floor. the coefficient of kinetic friction between the block and the floor is μk = 0.25. if the block begins with a speed of 7.
