NTA Abhyas JEE Main2020PhysicsRotational MotionPractice
A uniform, thin cylindrical shell and solid cylinder roll horizontally without slipping. The speed of the cylindrical shell is v . The solid cylinder and the hollow cylinder encounter an incline that they climb without slipping. If the maximum height they reach is the same, find the initial speed v ' of the solid cylinder.
Options
- A4 3 v
- B3 4 v
- C3 5 v
- D5 3 v
Correct answer
A. 4 3 v
Step-by-step solution
K E = 1 2 m v 2 + 1 2 I ω 2 3 4 m v 1 2 = m v 2 2 v 1 v 2 = 4 3
