Q1. A vector {vec A} has a magnitude of 40.0 {rm m} and points in a direction 20.0 ^circ below the positive x axis. A second vector, {vec B}, has the magnitude of 75.0 {rm m} and points in a direction 50.0 ^circ above the positive x axis.

Q2. A golf ball with an initial angle of 34? lands exactly 240 m down the range on a level course. The acceleration of gravity is 9.81 m/s2.

Neglect air friction, what initial speed would achieve this result?
