- Homework Statement
- A cylindrical body pivoting around a base strikes with the other a small metal sphere laying still on the ground. The cylinder is 1m long and 0.1m wide, with mass of 5kg - whereas the sphere is 1m across and 1kg heavy. Supposing the cylinder was rotating at 90deg/s, this translates to a tangential velocity of 1.57m/s where the impact happened.

- Relevant Equations
- How can I find the kinetic energy transferred in the form of rotational KE to the sphere from the cylinder? What about the translational KE of the sphere post-collision?

The cylinder in question would have a moment of inertia of ~1.67kg*m² and rotational KE of 2.058J. At the point of impact also, assuming the body hits the sphere at a 90deg angle after traversing 90deg of displacement, it should(?) exert a force of 1.31N - enough to give an acceleration of 1.31m/s².

How should I move from this point onward to get the desired data?
