FS = KAx 1) A rubber band is stretched from its resting position a distance of 0.1 m. If the spring constant is k = 2.5 N/m, what is the force being exerted on the rubber band? 2) If a spring is stretched a distance of 0.25 m with a force of 20 N, what is the value of the spring constant k? 3) If the spring constant k of a pogo stick is 3500 N/m and the weight of the person on the pogo stick is 700 N, how much is the spring in the bottom of the pogo stick compressed? 4) A spring (k = 2.3 N/m) is attached to an object of mass = 10 kg. If the object is hung from the ceiling by this spring, how much would the spring be stretched? 5) What is the elastic force a spring will exert if it has k =175N/m and is stretched 30cm
