A small ball is put into a cone and made to move at constant speed v in a horizontal circle of constant radius r. (See figure below.) (a) What is the ball’s centripetal acceleration? (b) What is its tangential acceleration? (c) What force can counteract the force of gravity so that the ball keeps moving in a horizontal circle? (d) Use these insights to determine the height h the ball is circling above the bottom of the cone. [Hint: This is equivalent to finding the angle the cone makes with its vertical axis.]

Modern roller coasters have vertical loops like the one shown in the figure below. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. What is the speed, in m/s, of the roller coaster at the top of the loop if the radius of curvature there is 19.0 m and the...
