Consider a frictionless ramp on which a smooth object is made to slide down from an initial height \(h\). The distance \(d\) necessary to stop the object on a flat track (of coefficient of friction \(\mu\) ), kept at the ramp end is
- A \(h / \mu\)
- B \(\mu\) is
- C \(\mu^2 h\)
- D \(r^2 \mu\)
Answer & Solution
Correct Answer
(A) \(h / \mu\)
Step-by-step Solution
Detailed explanation
From the conservation of energy, \[ \begin{aligned} m g h & =\mu m g d \\ d & =\frac{h}{\mu} \end{aligned} \]
