1) Convert a speed of 0.200 cm/s into units of km/year (follow the rules of significant figures in final your answer). [1] 2) Find the x- and y-components of a 25.0 m displacement vector with a bearing of [N 70 W] [1] 3) Add the following two vectors 30 m/s [E 30 N] and 20 m/s [W 30 N] [2] 4) A projectile is launched at velocity (v) and angle (O). Find an expression for the range (Adx) in terms of v, O, and g only. (Note: bold letters represent another way of writing a vector). [3] 4b) use your new expression/formula to find the range for an object launched at 120 m/s and 31 degrees.
