What is the total energy of a 300-g mass that is attached to a horizontal spring with a force constant of 260 N/m and oscillates along a frictionless horizontal surface with an amplitude of 8.0 cm?
A)21 J
B)0.83 J
C)2.4 J
D)1.6 J
E)6.2 J

Question

Quizplus · Accepted Answer

The total energy in a spring-mass system is given by the formula E = (1/2)kA^2, where k is the spring constant and A is the amplitude. Substituting the given values: E = (1/2)(260 N/m)(0.08 m)^2 = 0.83 J.
