Light of wavelength 659.4 nm is emitted by a star. The wavelength of this light as measured on Earth is 661.4 nm. How fast is the star moving with respect to Earth?
______________km/s
A spring with spring constant 13 N/m hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 8.5cm and free. The ball makes 26 oscillations in 18 s seconds.
The position of a particle is given in cm by x = (5) cos 5?t, where t is in seconds. Find the maximum acceleration of the particle
