Suppose an anemometer mounted at a height of 10 m on a level field with tall grass shows an average windspeed of 6 m/s. a. Assuming Rayleigh statistics and standard conditions (150C and 1 atm), estimate the average wind power (W/m2 ) at a height of 80 m. b. Suppose a 1300 kW wind turbine with 60 m rotor diameter is located in those 80 m winds. Estimate the annual energy delivered (kWh/yr) if you assume the turbine has overall efficiency of 30%. c. What would the turbineâs capacity factor be?
A major leaguer hits a baseball so that it leaves the bat at a speed of 30.0m/s and at an angle of 38.2degrees above the horizontal. Calculate the horizontal component of the baseball's velocity at an earlier time calculated in part (A)
A particle of charge Q is fixed at the origin of anxy coordinate system. At t = 0 a particle(m = 0.776 g, q = 5.04 µC is located on thex axis at x = 18.7 cm, moving with a speed of39.8 m/s in the positive y direction.
A simple pendulum has a mass of 0.250kg and a length of 4.00 m. It is displacedthrough an angle of 11.0° and then released. Solve this problem by using the simple harmonic motion model for the motion of the pendulum.
