A 45* wedge is pushed along a table with constant acceleration A. A block of mass m slides without friction on the wedge.Find its acceleration.
ans. If A=3g, d^2y/dt^2=g
where co-ordinates are:v along the dirn. of A and y perpendicular to it.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
