A car of mass \(1000 \mathrm{~kg}\) having a velocity of \(10 \mathrm{~ms}^{-1}\) collides a horizontally mounted spring. If the spring constant is \(4000 \mathrm{Nm}^{-1}\), then the maximum compression of the spring is

  1. A \(25 \mathrm{~m}\)
  2. B \(15 \mathrm{~m}\)
  3. C \(5 \mathrm{~m}\)
  4. D \(10 \mathrm{~m}\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(5 \mathrm{~m}\)

Step-by-step Solution

Detailed explanation

Mass of car, \(m=1000 \mathrm{~kg}\) Velocity, \(v=10 \mathrm{~m} / \mathrm{s}\) Spring constant, \(\mathrm{k}=4000 \mathrm{Nm}^{-1}\) Apply the conservation of energy \(\frac{1}{2} m v^2=\frac{1}{2} k(\Delta x)^2\)…
