A spring having with a spring constant 1200 N m–1 is mounted on a horizontal table as shown in Fig. 13.19. A mass of 3 kg is attached to the free end of the spring. Let us take the position of mass when the spring is unstretched as x = 0, and the direction from left to right as the positive direction of x-axis.Give x as a function of time t for the oscillating mass if at the moment we start the stopwatch (t = 0), the mass is at the mean position,

Options

  1. Ax=\sin 20t
  2. Bx=2\sin 40t
  3. Cx=2\sin 20t
  4. Dx=\sin 40t

Correct answer

C. x=2\sin 20t

Step-by-step solution

Correct Option is : (C)
x=2\sin 20t
