A 500-kg package slides 1.50 m down a long ramp that is inclined at 24.0 degree below the horizontal. The coeficient of kinetic friction between the package and the ramp is uk+0.310.
Calculate a) the wok done on the package by fiction
b) the wok done on the package by gavity
c) the work done on the package by the nomal force
d) the total work done on the package
e) if the package has a speed of 2.20 m/s at the top of the ramp, what is the its speed after sliding 1.5 m down the ramp?

A bat at flying east at 30 m/s sends out ultrasonic waves at 60kHz and receives them returned from an object moving east at 35.0 m/s, What is the sound frequency of the reflected wave as heard by bat
On a cello, the string with the largest linear density (1.54 10-2 kg/m) is C string. This string produces a fundamental frequency of 63.4 Hz and has the length of 0.795 m between the two fixed ends. Find tension in the string.
On windy days it sways with a frequency of 0.21 , and the acceleration of the top of the building can reach 2.4 of the free-fall acceleration, enough to cause discomfort for occupants.
First work out the momentum before and after hitting the table. Don't forget the gravitational force.
