A block of mass \(5\ \text{kg}\) slides down a rough incline that is \(30^{\circ}\) to the horizontal and \(4\ \text{m}\) long. The coefficient of kinetic friction between the block and the plane is \(0.20\). The block starts from rest at the top of the incline. Determine the power supplied by the weight of the block at the instant it reaches the bottom of the incline. Give your answer in watts (W) to three significant figures.

A. 1.02\times10^{2}\ \text{W}

Correct Answer B. 1.24\times10^{2}\ \text{W}

C. 1.36\times10^{2}\ \text{W}

D. 9.81\times10^{1}\ \text{W}

Correct Answer

Correct Option:

1.24\times10^{2}\ \text{W}
