An object of uniform density rolls up the curved path with the initial velocity \(v_0\) as shown in the figure. If the maximum height attained by an object is \(\dfrac{7v_0^2}{10g}\) (\(g\) = acceleration due to gravity), the object is a _______.
- A solid cylinder
- B ring
- C disc
- D solid sphere
Answer & Solution
Correct Answer
(D) solid sphere
Step-by-step Solution
Detailed explanation
By the law of conservation of mechanical energy, the total initial kinetic energy of the rolling object is converted into potential energy at the maximum height. Total initial kinetic energy for an object rolling without slipping is given by:…
