Hooke's Law in physics states that if a spring at rest (equilibrium position ) has a weight attached to it, then the distance the spring stretches is directly proportional to the force (weight). F = kx Where F is the force in Newtons(N), x is the distance stretched in meters (m), and k is the spring constant (N/m).A force of 352 N will stretch the spring 22 cm. How far will a force of 288 stretch the spring? Round to two decimal places.
