You have a light spring which obeys Hooke's law. This spring stretches 2.46 cm vertically when a 2.00 kg object is suspended from it. Determine the followmg. (a) the force constant of the Spring (in Nfrn) E m (b) the distance (in cm) the spring stretches if you replace the 2.00 kg object with a 1.00 kg object :cm {:2} the amount of work (In J) an external agent must do to stretch the spring 960 cm from its unstretched pomtion :1
