A block is rotating in contact with vertical wall (rotor) as shown. Find the minimum value of `omega` so that the block does not slide down.

Find the maximum value of force F such that the block shown in the figure does not move

A block of mass m is dropped onto a spring of constant k from a height h . The second end of the spring is attached to a second block of mass M as shown in figure. Find the minimum value of h so that the block M bounces off the ground. If the block of mass m sticks to the spring immediately after it comes into contact with it.

What is the value of the force vecF to be applied horizontally on a block of mass 5 kg which is in contact with a wall, as shown in the figure. (Take g = 10 m//s^(2) ) such that it does not fall down. The coefficient of friction between the block and the wall is 0.4.

A person stands in contact against the inner wall of a rotor of radius r. The coefficient of friction between the wall and the clothing is mu and the rotor is rotating about vertical axis. The minimum angular speed of the rotor so that the person does not slip downward is
