A small block with mass m is placed inside an inverted conethat is rotating about a vertical axis such that the time for onerevolution of the cone is T. the walls of the cone make an angle Bwith the vertical. The coefficient of static friction betweenthe block and the cone is ?. Draw a free body diagram.If the block is to remain a constant height h above the apex of thecone, what are the maximum and minimum values of T?
A child in a boat throws a 5.40 kg package out horizontallywith a speed of 10.0 m/s, in the figure. Calculate the velocity ofthe boat immediately after, assuming it was initially at rest. Themass of the child is 26.0 kg and that of the boat is 55.0 kg.
