... A 1.8-kg block sliding on a rough horizontal surface is attached to one end of a horizontal spring (k = 150 N/m) which has its other end fixed. If this system is displaced 25 cm horizontally from the equilibrium position and released from rest, the block first reaches the equilibrium position with a ...

Force (Weight versus Mass): Newtons 2nd Law
... If an object is slowing down, a force that was moving it forward must be decreasing. When a force acts on a moving object in the direction opposite the object's direction of motion, the object will move at a constant speed for a while and then slow down. Moving objects stop when they run out of forc ...
