Question #68240
a 15.0kg fish swimming at 1.1 m/s suddenly gobles up a 4.5 kg fish that is initially stationary. neglect any drag effects of the water. you can consider this event as acollision a) find the speed of the large fish just after it eats the small one b) how much mechanical energy was dissipated during this meal ? is this collision elastic? suppose an ice skater is spinning at 0.800rev/s with her arms extended. she has a moment of inertia of 2.34kg.m2 with her arms extended and of 0.363kg.m2 with her arms close to her body with respect to the axis of rotation a) what is her angular velocity in revolutions per second after she pulls in her arms b) compare her rotational kinetic energy before and after she moves her arms. if there is a difference, explain
