Question 5 NECO • 2017 • PHYSICS • essay

A 2.0 kg block is released from rest at the top of a smooth inclined plane that makes an angle of 30\(^\circ\) with the horizontal. The plane is 5.0 m long. At the bottom of the plane the block compresses a horizontal spring of spring constant \(k = 800\ \text{N·m}^{-1}\). The coefficient of kinetic friction between the block and the plane is 0.15. Assume \(g = 10\ \text{m·s}^{-2}\).

Question Parts

( a )

Calculate the work done by gravity on the block as it moves down the plane.

( b )

Determine the work done against friction during the motion down the plane.

( c )

Find the maximum compression of the spring.

( d )

Compute the average power delivered by the block to the spring during the compression, assuming the compression occurs over a time interval of 0.40 s.
