SUMMARY

The discussion focuses on the principles of simple harmonic motion (SHM) as it relates to a 2.6 kg block attached to a horizontal spring. The maximum velocity of the block can be determined using the formula for SHM, which incorporates the spring constant and amplitude. The mechanical energy of the system is calculated using the formula E = 1/2 k A², where k is the spring constant and A is the amplitude, which is given as 2 cm. The wave function described is a sine wave that crosses the x-axis at specified intervals, indicating periodic motion.

PREREQUISITES
  • Understanding of simple harmonic motion principles
  • Familiarity with spring constant calculations

A 2.6 kg block is attached to a horizontal spring and undergoes simple harmonic motion on a frictionless surface according to the graph shown above.

(a) What is maximum velocity of the box?


(b) What is the mechanical energy of the box?

now the wave is -sin wave but crosses the x-axis at 4,8,12,16,20,24 and has an amplitude of 2 cm
