Q. A Ferris wheel with radius 14.0 m is turning about a horizontal axis through its center. The linear speed of a passenger on the rim is constant and equal to 7.81 m/s.
What is the magnitude of the passenger's acceleration as she passes through the lowest point in her circular motion?
What is the direction of the passenger's acceleration as she passes through the lowest point in her circular motion?
What is the magnitude of the passenger's acceleration as she passes through the highest point in her circular motion?
How much time does it take the Ferris wheel to make one revolution?
Find the change in momentum of a 1080 {rm kg} car that increases its speed from 5.0 {rm m/s} to 14.5 {rm m/s} in a time of 11 {rm s} while travelling in the same direction.
Six artificial satellites complete one circular orbit around a space station in the same amount of time. Each satellite has mass and radius of orbit. The satellites fire rockets that provide force needed to keep a circular orbit around the space stat..

A second fragment, who's mass is 3.4 kg, moves away from the point of explosion with a speed of 418 m/s along the negative x axis. What is the speed of the third fragment? Ignore effects due to gravity.
What is the wavelength of the waves emitted by source? What is the difference in frequency between the directly radiated waves and the waves reflected from a whale traveling straight toward the ship at 4.95 ? Assume that the ship is at rest in the..
A cart of mass M = 1.2 kg can roll without friction on a level track. A light string draped over a light, frictionless pulley connects the cart to a hanger with mass m = 0.5 kg. The cart is released from rest, allowing it to roll, pulled by falling h..
If you weigh 690 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 25.0 km.
A 32.0 kg hammer strikes a steel spike 2.70 cm in diameter while moving with speed of 24.0 m/s. The hammer rebounds with speed 11.0 m/s after 0.110 s. What is an average strain in the spike all through the impact.
Modeling the optical trap as a Hookean spring, evaluate the trap stiffness using the Boltzmann distribution. Determine the sphere diameter by comparing the Stokes drag and the tweezer force that balances the drag.
Explain how Gestalt psychologists understand perceptual organization, including the discussion of form perception, depth perception, and perceptual constancy.
A skier is accelerating down a 30.0 degree hill at 1.8 m/s^2. How long will it take her to reach the bottom of the hill, assuming she starts from rest and accelerates uniformly, if elevation change is 325 m.
