A force F=a+bx acts on a particle in the x-directioin, where a and b are constants. Find the work done by this force during a displacement form x=0 to x=d .

A rod of mass m and length L , lying horizontally is free to rotate about a vertical axis through its centre. A horizontal force of constant magnitude F acts on the rod at a distance of L/4 from the centre. The force is always perpendicular to the rod. Find the angle rotated by the rod during the time t after the motion starts.
