Two sites on the same river have been surveyed as a place to build a dam. The dam will be part of a hydroelectric power plant. Site A is at the top of a 50-meter waterfall. Site B is at the top of a 35-meter waterfall. Which answer correctly describes where the water will have the greater gravitational potential energy to be converted into electricity?
A. Site A
B. Neither site has gravitational potential energy to convert to electricity.
C. Both sites will produce the same amount of electricity as the water flows over the water fall.
D. At both sites the water has the same gravitational potential energy.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j. b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
