What is the cars speed at the bottom of the dip?It takes a time t = 0.65 s for a record to revolve on a record player once. A particular point on the record moves past the needle at a speed of vn = 0.81 m/s. a)What is the radius at which the needle is in contact with the record in m? b)What is the tangential speed v2 of a point on the record that is at r2 = 0.05 m in m/s?In an amusement park ride, a child stands against the wall of a cylindrical room that is then made to rotate. The floor drops downward and the child remains pinned against the wall. If the radius of the room is 2.15 m and the relevant coefficient of friction between the child and the wall is 0.600, with what minimum speed is the child moving if he is to remain pinned against the wall? 07.26 m/s O3.93 m/s O 12.1 m/s 5.93 m/s 9.80 m/s

- A car of mass m is rounding a banked curve with radius R and banking angle 0. The curve is icy, so there is no friction between the tires and the surface. At what speed must the car take the turn in order for it not to slide up or down the incline? R Top View. Gravity is into the paper. √8 g Side View. The velocity is into the paperA bucket of water with a mass of 2.36 kg is attached to a rope that is wound around a cylinder. The cylinder has a mass of 3.00 kg and is mounted horizontally on frictionless bearings. The bucket is released from rest. A) Find the speed of the bucket after it has fallen through a distance of 0.800 m. in m/s B) What is the tension in the rope? in N C) What is the acceleration of the bucket? Enter a positive value if the acceleration of the bucket is upward and enter a negative value if the acceleration of the bucket is downward. in m/s^2In 1956, Frank Lloyd Wright proposed the construction of a mile-high building in Chicago. Suppose the building had been constructed. Ignoring Earth’s rotation, find the change in your weight if you were to ride an elevator from the street level, where you weigh 600 N, to the top of the building.
- Figure P9.75 shows a 100 g puck revolving at 100 rpm on a 20-cm-radius circle on a frictionless table. A string attached to the puck passes through a hole in the middle of the table. The end of the string below the table is then slowly pulled down until the puck is revolving in a 10-cm-radius circle. How many revolutions per minute does the puck make at this new radius?In the game of tetherball, a 1.25-m rope connects a M = 0.850-kg ball to the top of a vertical pole so that the ball can spin around the pole as shown in the figure below.
