A spaceship is approaching a space station at a speed of 2.55 multiply.gif 105 m/s. The space station has a beacon that emits green light with a frequency of 5.95 multiply.gif 1014 Hz.
(a) What is the frequency of the beacon observed on the spaceship? (Carry five digits in these calculations. Use c = 2.9979 multiply.gif 108 m/s for the speed of light. State your answer to five significant figures.) WebAssign will check your answer for the correct number of significant figures.
Hz
(b) What is the change in frequency?
A simple pendulum consists of a bob of mass 1.8kg attached to a string of length of 2.5m. The pendulum is held at an angle of 30 degrees from the vertical by the light horizontal string attached to a wall.

Light is an electromagnetic wave and travels at a speed of 3.00 x 10^8 m/s. The human eye is most sensitive to yellow-green light, that has a wavelength of 5.45 x 10^-7m. How you find the frequency of this light.
Suppose you walk 3.97 m down a 30° incline while holding a 1.05 kg block. The 3.97 m distance is measured as a displacement along the incline; not as a vertical change in height. How much work do you do on the block as you walk down the incline.
If you are given a velocity versus time graph, and v initial is given, how do you calculate instantaneous acceleration
Two blocks are connected by a string. The smooth inclined surface makes an angle of 35 degrees with the horizontal, and the block on the incline has a mass of 5.7 kg . The mass of the hanging block is = 2.9 kg.
