You throw a ball upwards at 15 m/s, what will be its velocity 2.0 seconds later? b) How high will it be above where you released it?

c) How long will it take to reach its highest point?

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
