Worksheet: Simple Harmonic Motion as a Function of Time

Q1:

The figure shows a simple pendulum consisting of a ball attached to the end of a light inextensible string of length 165 cm. The pendulum started moving from rest from point 𝐴 oscillating through an angle of 2 πœƒ , where t a n πœƒ = 4 3 . Find the speed of the ball at the point 𝐡 , given that it is the midpoint of the ball’s path. Take the acceleration due to gravity 𝑔 = 9 . 8 / m s 2 .

  • A 4 2 √ 1 1 0 cm/s
  • B 1 4 √ 3 3 0 cm/s
  • C 7 0 √ 6 6 cm/s
  • D 2 8 √ 1 6 5 cm/s
