After an impact involving a non-functioning satellite, a paint chip leaves the surface of the satellite at a velocity of +96m/s for 10 seconds.Then the object is hit by an asteroid and the force causes a 180 degree turn and the chip moves for 15 seco..
A string with a length of 0.5 meters is vibrating with a frequency of 100 Hz and it forms a standing wave at the fundamental mode with a velocity of 100 m/s. What is the new frequency of vibration on the sting
A physics student has designed a winter game. He has a platform 4.6 meters high with a rope tied to a tree at the same height, how fast are the boys and the sled moving after they "collide"
A particular guitar string is supposed to vibrate at 200Hz, but it is measured to actually vibrate at 209Hz. By what percent should the tension in the string be changed to get frequency to the correct value.
