A hydroelectric power plant has a dam 100 ft high, and water can flow through the dam and water turbines at 1 million lbm per minute over a 60-ft drop. If the turbines can convert the loss in potential energy of the water into electric power at an efficiency of 70%, how much power can the facility produce in megawatts? (Note: 550 ft ·lbf/s = 1 hp = 0.746 kW)

A 5.00-g bullet moving with an initial speed of 450 m/s passes through a 1.00-kg block, as shown in the figure. The block is initially at rest on a frictionless, horizontal surface and is connected to a spring that has a spring-force constant of 900 N/m. The block moves a distance d = 3.34 cm to the right after the collision. Note that the block only starts moving after the bullet has completely passed through the block. IWW d Round...
