4. A cat attached to an axle is initially at rest when a fuel-oxidizer explosion spins it through 2.00 revolutions, all while a nozzle with a valve damaged in the blast blows rocket propellant out of a port in the side of the cat, forcing it to undergo an angular acceleration of -9.81 rev/s2 in the opposite direction. At that 2.00 rev point (mentioned above), the angular acceleration has overcome the cat's initial rotational velocity and brought it to a momentary halt, before forcing it back in the opposite rotational direction. How fast was the cat spinning right after it underwent the explosion (before the propellant slowed its spin)? b. How long did it take the cat to get to the 2.0 rev point furthest away from its initial angle? e a. C. How fast was the cat spinning after it spun all the way back to its starting point? d. Consider that the tip of the cat's tail is stretched out 20.0cm away from the axis of rotation about which the cat is rotating. What is the tangential velocity v of the cat's tail when the cat first starts spinning, after the explosion? What is the centripetal acceleration of the cat's tail at that moment?

2.00 revolutions, all while a nozzle with a valve damaged in the blast blows rocket

of -9.81 rev/s2 in the opposite direction. At that 2.00 rev point (mentioned above), the
angular acceleration has overcome the cat's initial rotational velocity and brought it to a
momentary halt, before forcing it back in the opposite rotational direction.
