Wind speed is rounded off to the nearest 5 knots and is symbolized by "feathers" drawn on the clockwise side of the wind-direction shaft. A full feather represents 10 knots (11.5 mph) and half feathers indicate 5 knots. A pennant indicates 50 knots and a circle drawn around the station circle signifies calm conditions. In this case, the reported wind speed is

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
