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 75 N will stretch the spring 15 cm. How much force to the nearest Newtons is required to stretch the spring 33 cm?


A) 34 N
B) 165 N
C) 37,125 N
D) 2 N
