1. Use to-scale vector drawings to determine the resultant of the vectors given. Be sure to state your scale and state your answer in proper vector notation. 100 m/s[N50∘E]+50 m/s[E75∘S]−30 m/s[N65∘E] B. VECTOR COMPONENTS PLEASE PUT A CIRCLE OR BOX AROUND YOUR FINAL ANSWER. YOU ARE NOT REQUIRED TO WRITE A SENTENCE. SIGNIFICANT FIGURES ARE IMPORTANTI Show all your work for full marks. (Partial work=partial marks)
2. Find the components of the following vectors using trigonometric functions: a. The wind is blowing at 77 km/hN25∘W b. A car accelerates at 4.55 m/s2 at a bearing of 117 C. ADDITION OF VECTORS (USING RIGHT ANGLE TRIGONOMETRY)
3. A little bird flies at 5.5 m/s [ 25∘ E but the wind is blowing at 0.80 m/s [South]. What is the bird's resultant velocity?
4. A jetliner flies with an airspeed of 665 km/hr directed at [W57.5∘ S] The wind speed is 120 km/hr directed at [N 30.0∘ W] Determine the groundspeed of the jetliner. State this as a velocity vector. [ 4 marks] - Airspeed is the speed of the aircraft relative to the air. The air can be moving -i.e., the wind - Wind speed is the speed of the wind relative to the ground - Groundspeed is the velocity of the aircraft relative to the ground.
