- A Small 10 0 G Bug Stands At One End Of A Thin Uniform Bar That Is Initially At Rest On A Smooth Horizontal Table The O 1 (28.03 KiB) Viewed 37 times
A small 10.0 g bug stands at one end of a thin uniform bar that is initially at rest on a smooth horizontal table. The other end of the bar pivots about a nail driven into the table and the bar can rotate freely on the table, without friction. The bar has mass 50.0 g and is 100 cm in length. The bug jumps off in the horizontal direction, perpendicular to the bar, with a speed of 20.0 cm/s relative to the table. Note: to be very clear, this bar rotates horizontally with respect to the gravitational field- not vertically. a) What is the angular speed of the bar just after the frisky insect leaps? b) What is the total kinetic energy of the system just after the bug leaps?
