48. A force is applied to a spring causing it to stretch. If the applied force is halved, the potential energy stored in the spring will be (1) halved (2) doubled (3) quartered (4) quadrupled 49. A vertically hung 0.50-meter-long spring is stretched from its equilibrium position to a length of 1.00 meter by a weight attached to the spring. If 15 joules of elastic potential energy are stored in the spring, what is the value of the spring constant? (1) 30. N/m (2) 60. N/m (3) 120 N/m (4) 240 N/m 50. A spring has a spring constant of 120 newtons per meter. Calculate the elastic potential energy stored in the spring when it is stretched 2.0 centimeters.
