The diagram represents the path of a ball that has been thrown upward. Discuss how the kinetic energy (KE), gravitational potential energy (GPE), and total mechanical energy (ME) change between points A (where the ball is thrown from), B (the highest point reached by the ball), and C (where the ball hits the ground). Ignore friction between the ball and the air. (3 points)

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

What are igneous intrusions and extrusions

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.
