Velocity & Acceleration in SHM

The velocity of a particle executing SHM varies with displacement (xx) as 4v2=50−x24v^2 = 50 - x^2. The time period of oscillations is x/7x/7 s.

The value of xx is (Take π=22/7\pi = 22/7)

Show answer and solution

Answer: (c)

  1. Compare v2=14(50−x2)v^2 = \frac{1}{4}(50 - x^2) with v2=ω2(A2−x2)v^2 = \omega^2(A^2 - x^2): ω2=14\omega^2 = \frac{1}{4}, ω=12\omega = \frac{1}{2} rad/s.
  2. T=2πω=4π=4×227=887T = \frac{2\pi}{\omega} = 4\pi = 4\times\frac{22}{7} = \frac{88}{7} s.
  3. x7=887⇒x=88\frac{x}{7} = \frac{88}{7} \Rightarrow x = 88.
  4. So the answer is (c) 88.
