A 0.110-kg ball (ball x) moving at 1.20 m/s to the right, collides head-on with an identical ball (ball Y) moving to the left at a velocity of 0.600 m/s. Ball Y rebounds and reverses direction at a velocity of 0.800 m/s. What is the velocity of ball X following the collision? A 0.200 m/s to the left
B. 0.0924 m/s to the right
C. 0.0880 m/s to the right
D. 0.00440 m/s to the left​

Ahowler monkey is the loudest land animal and, under some circumstances, can be heard up to a distance of 4.6 km. assume the acoustic output of a howler to be uniform in all directions and that the threshold of hearing is 1.0 × 10-12 w/m2. what is the acoustic power emitted by the howler

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?
