```				   A uniform ladder of mass 10 kg leans against a smooth vertical wall making an angle 53 with it. the other end rests on a floor. Find the normal force and frictional force that the floor exerts on the ladder.

Torque about B is taken as
N1(AO)=W(CB)
Please explain the concept behind the above equation.

```										calculate  all the forces acting on center of mass of rod & net torque about center of mass
put both of these equal to zero (because there is neither translational nor rotational motion )and
then u will have 2 equations and two variables..
solve these equations and get the ans...

a ball is dropped on the ground from a height 10cm .if coifficient of restitution is 0.4, then find the height to which ball is rebound ?

Final velocity would be, v = root( 0 + 2g*10/100) = > root(2) m/s. From coeff. of restitution, v’ = ev = > 0.4*v Now let h be the height it rebounced then, 0^2 = (0.4v)^2 – 2gh h =...
