A block goes on a wedge which in turns goes on a horizontal table, as given in figure. The wedge angle is Φ.
As long as the wedge is in met with table, we have the trivial constraints that the vertical acceleration of the wedge is zero. To find the constraint, let x be the horizontal co-ordinate
of the end of the wedge and let y and x be the horizontal and vertical coordinate of the block as given then
(x -X) = (h - y) cot Φ
Even if the friction among the block and wedge affect their acceleration, above relation is remains as long as they are in contact.
A 25 N box is pulled vertically upward by means of a cord.Find the acceleration of the box if the tension in the cord is 35 N.
A pendulum is timed, first for 20 swings and then for 50 swings Time for 20 swings= 17.4s Time for 50 swings= 43.2s Calculate the average time per swing in each case.
INSTANTANEOUS ACCELERATION: The acceleration of the body at any certain instant during its motion is called to be an instantaneous acceleration.
To work out the gravitational potential energy of an object the equation is: GPE = m x g x h Where: m = the mass of the object (kg) g = gravitational field strength (on earth tha
In the case of orientation polarization we have material with built _in dipoles that are independent of each other, i.e. they can rotate liberally in sharp distinction with ionic p
