A wind turbine on a wind farm turns in response to a force of high-speed air resistance, R=0.5DρAυ2. The power available is P=Rυ=0.5Dρπr2υ3., where .υ is the wind speed and we have assumed a circular face for the wind turbine of radius r. Take the drag coefficient as D=1.0 and the density of air from the front endpaper . For a wind turbine having r=1.5 m, calculate the power available with (a) υ=8.0 m/s and (b) υ=24.0 m/s. The power delivered to the generator is limited by the efficiency of the system, about 25%. For comparison, a large American home uses about 2 kW of electric power.
A 30 kg child slides down a slide with h = 4.0 m and arrives at the ground with a speed of 6.0 m/s. The slide forms the arc of a circle with a radius of 21 m with the ground tangent to the bottom of the slide. Determine the average friction force acting on the child. Hint: Use h = R(1 - cos(θ)) and s = Rθ where θ is in radians and s = arc length.

And don't worry about whether the passengers would actually survive the trip. They are lightweight crash test dummies. NTC A cart of mass m= 347 kg is going around a circular loop-the-loop. There is no motor. The cart moves only under the influence of gravity. Ignore friction and let g = 9.81 meters per second squared. The loop has a radius of r meters. When the cart is at the top of the loop, the normal force on the cart (exerted by the track) pushes down on the cart with a force of N = 1,330 newtons. When it is at the bottom of the loop, the cart has a speed of 30.7 meters per second. What is the radius of the loop (in units of meters)?
