A sphere slides along a friction-free inclined surface n. The sphere slides from a height of n for the speed of the sphere once it reaches the point2. (b) 4.0m. (a) Develop an expression What is speed it has at that point when released from rest from the point1 ? The moment of inertia of the sphere is! = m Ans : = 7.5- S 2 4.0 m 2
