A \(5.0\) kg block is released from rest at the top of a \(30^{\circ}\) incline that is \(4.0\) m long. The coefficient of kinetic friction between the block and the incline is \(0.20\). At the bottom of the incline the block compresses a horizontal spring of force constant \(800\) N m\(^{-1}\). (a) Find the maximum compression of the spring. (b) Determine the average power delivered by gravity to the block during its descent.

Answer Options

A. (a) Maximum compression \(x = 0.30\) m. (b) Average power supplied by gravity \(\approx 80\) W.
B. (a) Maximum compression \(x = 0.40\) m. (b) Average power supplied by gravity \(\approx 45\) W.
Correct Answer C. (a) Maximum compression \(x = 0.40\) m. (b) Average power supplied by gravity \(\approx 62\) W.
D. (a) Maximum compression \(x = 0.55\) m. (b) Average power supplied by gravity \(\approx 62\) W.
Correct Answer
C
Correct Option:
(a) Maximum compression \(x = 0.40\) m. (b) Average power supplied by gravity \(\approx 62\) W.
