A cylinder of mass \(12 \mathrm{~kg}\) is sliding on plane with an initial velocity \(20 \mathrm{~ms}^{-1}\). If the coefficient of friction between the surface and the cylinder is 0.5 , before stopping, the cylinder describes a distance of
- A \(40 \mathrm{~m}\)
- B \(5 \mathrm{~m}\)
- C \(20 \mathrm{~m}\)
- D \(10 \mathrm{~m}\)
Answer & Solution
Correct Answer
(A) \(40 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
Given that, mass of cylinder, \(m=12 \mathrm{~kg}\) Initial velocity, \(u=20 \mathrm{~m} / \mathrm{s}\) Coefficient of friction, \(\mu=0.5\) We know that, the retardation produced by friction \(=a=-\mu g=-0.5 \times 10=-5 \mathrm{~m} / \mathrm{s}^2\) [using,…
