A Particle Moves Back and Forth Along the X Axis

question 55

Multiple Choice

A particle moves back and forth along the x axis from x = -x_m to x = +x_m, in simple harmonic motion with period T.At time t = 0 it is at x = +x_m.When t = 0.75T:

• A)it is at x = 0 and is traveling toward x = +x_m
• B)it is at x = 0 and is traveling toward x = -x_m
• C)it is at x = +x_m and is at rest
• D)it is between x = 0 and x = +x_m and is traveling toward x = -x_m
• E)it is between x = 0 and x = -x_m and is traveling toward x = -x_m
