n old streetcar rounds a flat corner of radius 6.00 m, at 21.0 km/h. What angle with the vertical will be made by the loosely hanging and straps? Number i 8.79 Units °(degrees)

A 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^2

In a charming 19th-century hotel, an old-style elevator is connected to a counterweight by a cable that passes over a rotating disk 2.00 m in diameter (Figure 1). The elevator is raised and lowered by turning the disk, and the cable does not slip on the rim of the disk but turns with it. Part A At how many rpm must the disk turn to raise the elevator at 35.0 cm/s? Express your answer in revolutions per minute. Nνα ΑΣφ W = rpm Part B Figure 1 of 1 To start the elevator moving, it must be accelerated at g. What must be the angular acceleration of the disk, in rad/s? Express your answer in radians per second squared. Πν ΑΣφ ? Disk a = rad/s? Counterweight Part C Elevator

Part A, B, and C

A fighter pilot, whose mass is 65 kg, completes a vertical loop of radius R=450m with a constant speed v=261 m/s. At the top of the loop, determine the ratio of the apparent weight of the pilot to his regular weight, .WA/W =? Express your answer in SI units with zero decimal places. Take g=9.8 m/s². R

An airplane is flying in a horizontal circle at a speed of 441 km/h. If its wings are tilted 40° to the horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an "aerodynamic lift" that is perpendicular to the wing surface. m I 0

M

A small block with mass 0.0450 kg slides in a vertical circle of radius 0.0710 m on the inside of a circular track. There is no friction between the track and the block. At the bottom of the block's path, the normal force the track exerts on the block has magnitude 3.70 N Part A What is the magnitude of the normal force that the track exerts on the block when it is at the top of its path?

n a carbon monoxide (CO) molecule, the distance between the oxygen atom and the carbon atom is 1.13 × 10-10 meters. The mass of an oxygen atom is 16 atomic mass units (amu) and the mass of a carbon atom is 12 amu. How far from the oxygen (O) atom is the center of mass of the molecule, in meters? Justify your answer using your equations and rationale used.
