Find X


Expand








Supose we drop a 3kg object on a curved ramp (without friction). At the end of the ramp the surface is plain, with a constant strenght of k=100 N/m. At the end of it there's a device that will be compressed x metres on the impact.
a. Calculate X.
b. Does the object continue moving after hitting the device? If so, calculate the distance.

ANSWER: The object never made it because there's an elephant on the road.

FUNNY!  ;D
Spatial distortion is a serious problem deteriorating headphone listening.
Crossfeeders reduce spatial distortion and make the sound more natural
and less tiresome in headphone listening.
