a football is thrown directly toward a receiver with an initial speed of 18.0 m/s at an angle of 35 above the horizontal. at that instant, the receiver is 18.0 m from the quarterback. in what direction and with what constant speed should the receiver run to catch the football at the level at which it was thrown

Does this organism still meet the definition of a eukaryote ? why or why not?

The speed of light in a material is 0.50 c. what is the critical angle of a light ray at the interface between the material and a vacuum?

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?
