- A Father spinning a child on a merry-go round , he exerts a Force of 140 N, at a distance of 1.4 m. And does this over 1.5 revolutions. What is the rotational work done?Diving from a high cliff, Cliff begins bent in half ( I = 4 kg m2 ) with a moderate rotational speed of a half rotation per second. During the dive he tucks his mass inwards ( I = 0.8 kg m2 ); in this position, what rotational speed will he have?A baseball pitcher throws the ball in a motion where there is rotation of the forearm about the elbow joint as well as other movements.
- Is there a type of object that would spend more energy rotating than moving linearly? If so, which object? If not, which type of object will have the largest portion of rotational kinetic energy and how much will it have?Chapter 10: Dynamics of Rotational MotionThe angular velocity of a wheel increases from 100 to 30 10 s. The number of revolutions made during that time is (а) 600 (c) 1000 (b) 1500 (d) 2000
- As distance increases between most of the mass of an object and its center of rotation, does rotational inertia increase or decrease?What is the difference between the angular velocity of a second hand of a wrist watch compared to the second hand of a large clock towers second hand? What about both vs linear velocity? Explain both answersWhat is rotational non-impulse?
