JEE Main Physics question
A cylinder of mass 10 kg is sliding on a plane with an initial velocity of 10 m/s. If the coefficient of friction between the surface and cylinder is 0.5, then before stopping it will describe
Answer: (D)
Solution
Using v² = u² − 2μgs with v = 0: s = u²/(2μg) = (10)²/(2 × 0.5 × 10) = 100/10 = 10 m.
