Answers : (1)


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 =...
