PHYSICS 30 VECTOR ANALYSIS OF MOTION Q3 ASSIGNMENT DO YOUR WORK ON A SEPARATE PIECE OF PAPER PLEASE PUT A CIRCLE OR BOX AROUND YOUR FINAL ANSWER. YOU ARE NOT REQUIRED TO WRITE A SENTENCE. SIGNIFICANT FIGURES ARE IMPORTANT! SHOW ALL YOUR WORK FOR FULL MARKS. (PARTIAL WORK=PARTIAL MARKS) A. VECTOR DIAGRAMS .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. [5 marks] 100 m/s [N 50 E] + 50 m/s [E 75* $] - 30 m/s [N 65. 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 IMPORTANT! Show all your work for full marks. (Partial work=partial marks) 2. Find the components of the following vectors using trigonometric functions [4 marks]: . The wind is blowing at 77 km/h N 25* W b. A car accelerates at 4.55 m/s' at a bearing of 117* C. ADDITION OF VECTORS (USING RIGHT ANGLE TRIGONOMETRY) 3. A little bird flies at 5.5 m/s [N 25* E] but the wind is blowing at 0.80 m/s [South]. What is the bird's resultant velocity? [2 marks] 4. A jetliner flies with an airspeed of 665 km/hr directed at [W 57.5* 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.PHYSICS 30 VECTOR ANALYSIS OF MOTION D. PROJECTILE MOTION 5. Red Cross workers are dropping aid and food packages from their airplane, 1.00 km above ground. They are heading straight for their target drop location. The plane's velocity is 135 km/hr. From how far away should the aid workers drop the packages in order to hit their target? [3 marks] A motorcycle dare devil, Rex Russel made a record setting jump across Scary Canyon. The canyon's elevation was 35.0 m higher on the first side of the canyon than on the side he landed. If the initial velocity of Rex was 31.5 m/s @ 38.0' from the horizontal, what was Rex's final velocity? [4 marks] 35.0 m III O
