3) Exceeding question A ball is launched from a cennon at some angle e. The moment it leaves the cannon, it has a velocity in the x direction of 20m/s, and a
velocity in the y direction of 50m/s. What angle was the cannon fired at? Show
work in the box below. (hint, recall properties of right triangles)

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.)
