Vertical displacement of a plank with a body of mass m on it is varying according to the law `y=sinomegat+sqrt(3)cosomegat`. The minimum value of `omega` for which the mass just breaks off the plank and the moment it occurs first time after t=0, are given by (y is positive towards vertically upwards).

Vertical displacement of a plank with a body of mass 'm' on it is varying according to law y=sin omegat +sqrt(3) cos omegat . The minium value of omega for which the mass just breaks off the plank and the moment it occurs first arter t=0 are given by: (y "is positive vertically upwards")

A horizontal plane supports a plank with a bar of mass m placed on it and attached by a light elastic non-deformed cord of length l_0 , to a point O. The coefficient of friciton between the bar and the plank is equal to m . The plank is slowly shifted to the right until the bar starts sliding over it. It occurs at the moment when the cord derivates from the vertical by an angle theta . Find the work that has been performed by the moment by the frictional force acting on the bar in the reference frame fixed to the plane.

A particle of mass 'm' is moving in the x-y plane such that its x and y coordinate vary according to the law x = a sin omega t and y = a cos omega t where 'a' and 'omega' are positive constants and 't' is time. Find (a) equation of the path. Name the trajectory (path) (b) whether the particle moves in clockwise or anticlockwise direction magnitude of the force on the particle at any time t .
