A gymnast flipped in the air with a maximum angular velocity of 6.5 rad/s while maintaining a constant body position. What is the magnitude of the angular impulse (in kg*m^2/s) exerted by the floor on that gymnast when they stuck the landing (w = 0 rad/s) if they had a mass of 53.3 kg and a radius of gyration of 0.8 m?

a 60 kg gymnast leaves the ground with angular momentum about his transverse axis of 15 kg m2/s. His radius of gyration about the transverse axis is 0.7 m at take-off. During his subsequent somersault, he reduces his radius of gyration to 0.4 m. (a) What is the moment of inertia of the gymnast at take-off? During the somersault? (b) What is the angular velocity of the gymnast at take-off? During the somersault? (c) If it takes the gymnast 0.25...

Simone, a 47 kg gymnast, is performing the last tumbling pass of
her floor routine. The tumbling pass involves running as fast as
possible then jumping into the air to complete a double layout with
a twist (this exact maneuver, the double layout with a twist, is
not important, but a photo is provided on Canvas to show you what
this maneuver is). The instant before she jumps into the air, her
center of mass (COM) is 0.90 m above...

26.1) An object travels around a circle at constant speed. Which of the following quantities are constant? A) The object's linear momentum, B) The object's angular momentum, C) Both p and are constant D) Neither of p or are constant. 26.2) An object travels around a circle at constant speed. If the object is stopped and then rotated in the opposite direction at the same speed, its angular momentum, l, will be the same. A) True B) False

A gymnast doing a forward flip lands on the mat and exerts a 490 N · m torque to slow and then reverse her angular velocity. Her initial angular velocity is 12.0 rad/s, and her moment of inertia is 0.065 kg · m2. (Assume her final angular velocity is −12 rad/s.) (a) What time (in s) is required for her to exactly reverse her spin? (b) What is unreasonable about the result? (c) Which premises are unreasonable or inconsistent?

A child is riding an expensive skateboard with frictionless wheels at a constant velocity when the child runs straight into the centre of a door which has much more mass than the child. As a result, the door swings open slowly while the child and skateboard stop moving. Assume that the door has no friction. Which of the following quantities are conserved? (A) Mechanical energy. (B) Linear momentum. (C) Angular momentum (D) there are no conserved quantities (E) There are...
A moon of mass m orbits around a non-rotating planet of mass M with orbital angular velocity . The moon also rotates about its own axis with angular velocity .
1. A moon of mass \(m\) orbits around a non-rotating planet of mass \(M\) with orbital angular velocity \(\Omega\). The moon also rotates about its own axis with angular velocity \(\omega\). The axis of rotation of the moon is perpendicular to the plane of the orbit. Let \(I\) be the moment of inertia of the moon about its own axis. You can assume \(m<<M\)so that the center ofmass of the system is at the center of the planet.(a) What is...
