A Ferris wheel rotates at an angular velocity of 0.29 rad/s. Starting from rest, it reaches its operating speed with an average angular acceleration of 0.031 rad/s². How long does it take the wheel to come up to operating speed?

A particle has a mass of 1.88E-28 kg and it travels at a speed of 0.971c, where c is the speed of light. What is the energy of the particle, expressed in MeV. Keep three significant digits

A speeder tries to explain to the police that the yellow warning lights she was approaching on the side of the road looked green to her because of the Doppler shift. How fast would she have been traveling if yellow light of wavelength 580 nm had been shifted to green with a wavelength of 560 nm? Assume c=3x108 m/s and that light was moving not the car. Write your answer in percents of c rounded to a two decimals for example 1.25

Find the length and direction (when defined) of u xv and vxu. u = 5i - 2j - 6k, v= 6i – 6k The length ofuxvis

Calculate the speed of a proton and an electronic after each particle accelerates from rest through a potential difference of 355V.

Please Solve Correctly.

A particle has a mass of 1.88E-28 kg and it travels at a speed of 0.843c, where c is the speed of light.  What is the energy of the particle, expressed in MeV. Keep three significant digits

Please help with the solution to this problem using (km/s). I know we will use Hohmann Transfer and a combined plane change.    In the opening scene of the movie “Gravity” Dr Ryan Stone (Sandra Bullock) and Matt Kowalsky (George Clooney) are required to transit from the Hubble Space Telescope (Altitude 600 km, 28.5 degree inclination) to the International Space Station (Altitude 400 km, 51.6 degree inclination) using nothing but their Manned Maneuvering Units (MMU). An MMU has a delta V capability of about 30 m/s, and it would be impossible to perform this maneuver with so little delta V, but… a.) How much delta V would be required for this maneuver? b.) What if the maneuver did not require an inclination change (altitude change only?)

In a television tube electrons are accelerated through a voltage of 5000 volts. What is the speed of the electrons assuming that they were initially at rest? (Since this is Physics 222, do not use special relativity to calculate the answer even though these speeds are a fraction of the speed of light.) Express your answer to the nearest km/s.

The cosmic rays of highest energy are protons that have kinetic energy on the order of 1013 MeV. (a) From the point of view of the proton, how many kilometers across is the galaxy? (b) How long would it take a proton of this energy to travel across the Milky Way galaxy, having a diameter ~ 105 light-years, as measured in the proton’s frame?
