Russian ice skater, alina zagitova, spins her way to projected gold in the 2018 olympics. during one particular spin, she moves from a camel spin that rotates at about 95.0 rpm to a tight spin. if her rotational inertia changes from 129kgm² to 32.0kgm², what is the final spin rate of miss zagitova in rad/s and rpm

Aball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and passes the top of the window 0.20 s later. the window is 2.0 m high from top to bottom. what was the ball's initial velocity? the unit vector j^ is directed upward. how far is the bottom of the window from the launch position? how high does the ball rise above the launch position?

Which notation is used to represent an alpha particle? a. b. c. d.
