A 5.4 kg shot rolls along the ground at 15 ms and collides head on with a stationary shot which has a mass of 4.0 kg. The friction force is negligible during the collision After the collision, the 4.0 kg shot moves rolls forward at 2.4 ms 'in the same direction that ttle 5.4 kg shot was initially rolling. Calculate the velocity (size and direction) of the 5.4 kg shot after the collision ​

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?
