Question

Starting from rest, an object rolls down along an incline that rises by 3 units in every 5 units (along it). The object gains a speed of \(\sqrt{10}\) m/s as it travels a distance of 5/3 m along the incline. What can be the possible shape/s of the object?

Answer 1

Data : sin θ = 3/5 , u = 0, v = \(\sqrt{10}\) m/s, L = 5/3m, g = 10 m/s²

Therefore, the body rolling down is either a ring or a cylindrical shell.
