Question 4 NECO • 2024 • PHYSICS • essay

A block of mass 5.0 kg rests on a rough inclined plane that makes an angle of 30\(^\circ\) with the horizontal. The block is attached to a light string that passes over a smooth pulley at the top of the incline and is connected to a hanging mass M. The system is in equilibrium and the tension in the string is measured to be 30 N. The diagram of the system is shown in the force diagram.

Question Parts

( a )

Calculate the weight of the block and resolve it into components parallel and perpendicular to the plane.

( b )

Using the equilibrium condition, determine the normal reaction exerted by the plane on the block.

( c )

Find the value of the coefficient of static friction \(\mu_s\) between the block and the plane.

( d )

If the hanging mass M is increased until the block just begins to move up the plane, calculate the minimum value of M required. Assume the coefficient of static friction remains unchanged.
