Suppose that the angular velocity is constant as he pulls the string in.  Now calculate the force ratio  (Ff/Fo).  These are the numbers: ro = 5 meters rf = 4 meters vo = 9 m/s

Peg P is driven by the fork link OA along the curved path described by r 2.8.8 ft. At the instant = 1.3 rad, the angular velocity of the link is = 1.4 rad/s and the angular acceleration is 0=0.66 rad/s². For peg P at this instant, please find: radial acceleration a, a -10.55 transverse acceleration ag= magnitude of total acceleration a= m m m 5²

A large wind turbine (typical of the size and specifications of a turbine that you see in a modern wind farm) has three blades connected to a central hub. The blades are 50 m long and rotate at 10 rpm. What angular speed ω does this correspond to? What is the speed ν of the tip of a blade? What is the speed of a point 25 m from the hub?

A solid 0.6150 kg ball rolls without slipping down a track toward a vertical loop of radius ?=0.7350 m. What minimum translational speed ?minvmin must the ball have when it is a height H=1.111 m above the bottom of the loop in order to complete the loop without falling off the track? Assume that the radius of the ball itself is much smaller than the loop radius ?R. Use g=9.810 m/s^2 for the acceleration due to gravity.

What is the mass of each ball?
