A 2.0 kg mass is attached to the end of a horizontal spring (k = 50. N/m) and set into simple harmonic motion with an amplitude of 10. cm. What is the total mechanical energy of this system?
A) 2.5 J
B) 0.02 J
C) 0.25 J
D) 1.00 J
E) 25 J

Question

Quizplus · Accepted Answer

The total mechanical energy in a spring-mass system is given by E = (1/2)kA^2. Substituting k = 50 N/m and A = 0.1 m, E = 0.25 J.
