. A hockey puck of mass 200 g slides across level frictionless ice toward a curved \"ramp\" in the shape of a quarter circle. The puck's speed on the level surface is 6.0 m/s, and the radius of curvature of the ramp is 75 cm. Throughout this problem, you are V = 6'0 "1/5 % encouraged to add to and label things on the diagram. - (a) Consider the puck at point A, just as it begins to travel on the ramp. Find the magnitude of the normal force on the puck at point A. (Hint: it is NOT equal to the puck's weight) (b) While the puck slides on the curved ramp, there is a frictional force of average magnitude 1.5 N acting on it. When it reaches the top of the curved ramp, it continues upward into the air with negligible air resistance. How far above the top of the ramp does the puck rise before falling back down
