A small 10.0 g bug stands at oneend of a thin uniform bar that is initially at reston a smooth horizonta It able. The other end of the bar pivots abouta naildriven into the table and can rotate freely, without friction. The bar has mass 50.0 g and is 100 cm in, length. The bug jumps off in the horizontal d rection, perpendicular to the bar, with a speed of 20.0 cm/s relative to the table. What is the total kinetic energy of the system just afterthe bug leaps?
