A block is executing SHM on a rough on a horizontal surface under the action of an external variable force. The force is plotted against the position x of the particle from the mean position.

It is proposed to move a particle in simple harmionic motion on a rough horizontal surface by applying an external force along the line of motion. Sketch the graph of the applied force agains the position of the particle. Note that the applied force has two values for a given position depending on whether the particle is moving in positive or negative direction.

A block is sliding on a rough horizontal surface. If the contact force on the block is sqrt2 times the frictional force, the coefficient of friction is

A 5 kg block moves in a straight line on a horizontal frictionless surface under the influence of a force that varies with position as shown in the figure. Find the work done by this force as the block moves from the origin to x = 8m.
