CAPE Physics Unit 1 · 2007 (Specimen) · Paper 1 · Question Q30

Item 30 refers to the following diagram. A mass m, undergoes horizontal simple harmonic motion under the action of two springs as shown. Its equation of motion is a = -\frac{2k}{m}x and its amplitude is A. What is its MAXIMUM kinetic energy?

1. (A)\frac{1}{2} kA^2 / m
2. (B)2 m^2 A^2 / K
3. (C)2 k^2 A^2 / m
4. (D)kA^2

This question uses a figure or table from the paper — you'll see it when you practise.
