The blades on modern wind turbines are typically 20 to 40 meters in length. Two different turbines have their blades attached with one end at the center of rotation. Consider two points, each at the outer end of a blade on each of the turbines: one with a blade length of 21.2 m, and the other with a blade length of 42.6 m. Each blade is rotating with a constant angular speed of 3.83 rad/s, and the rotation is considered for 11.2 s.
a. What is the speed of each point in meters per second?
b. What is the angular distance traveled by each point?
c. What is the translational distance traveled by each point?
d. What is the magnitude of the centripetal acceleration that would iT experienced by an object located at each point?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
