Q1. Vector A has a magnitude of 9.10 units and makes an angle of 54.0° with the positive x-axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x-axis. Using graphical methods find the following.

Q2. A cargo plane is flying horizontally at an altitude of 11 km with a constant speed of 765 km/hr while a large crate slides out of the rear of the plane. How long does it take the crate to hit the ground? The acceleration of gravity is 9.81 m/s2. How far is crate from the aircraft when it hits the ground?
