A thin, light string is wrapped around the rim of a 3.75-kgkg, solid, uniform disk (similar to a puck on ice without friction) that is 33.0 cmcm in diameter. A person pulls on the string with a constant force of 98.00 NN tangent to the disk, as shown in the figure below (Figure 1). The disk is not attached to anything and is free to move and turn. Part B Find the linear acceleration of its center of mass. Express your answer in meters per second squared. Part D If the disk is replaced by a hollow, thin-walled cylinder of the same mass and diameter, what will be the linear acceleration of its center of mass? Express your answer in meters per second squared.

Suppose a roadway is banked at an angle of θ = 11o. A m = 920-kg car rounds a circular roadway. The turn radius of the roadway is r = 67.9 m. (Image Here) (1) Find the minimum tangential speed that enables the car to make the turn. Neglect friction. (2) Now, suppose there is static friction between tires and the road. If the car were to travel faster than the speed you found in part (a), in what direction would static friction between the tires and road need to point (toward the center or away) such that the car can make the turn? Explain. What if the car were to travel slower than the speed you found in part(3) In what direction would static friction point then?
