A 10 ~kg collar is attached to a spring (spring constant 600 ~N / m ), it slides without friction over a horizontal rod. The collar is displaced from its equilibrium position by 20 ~cm and released. What is the speed of the oscillation?

Options

  1. A60 0.2 ~m / s
  2. B60 0.2 ~m / s
  3. C60 2 ~m / s
  4. D6 0.2 ~m / s

Correct answer

A. 60 0.2 ~m / s

Step-by-step solution

Given, amplitude, A=20 ~cm =0.2 ~m Force constant, k=600 Nm ⁻¹ Maximum speed of oscillation, aligned v_ &=A &=A k m [ = k m ] &=0.2 600 10 =0.2 60 ~m / s aligned
