السلام عليكم
كيف حالكم اخواني ؟؟
انا طبعا عندي تسلم واجب يوم السبت عن Vectors
وهو عبارة عن 30 سؤال
طبعا تمكنت من حل 29 سؤال
وباقي لي سؤالين
لم استع من حلهم
ياليت الى يقدر يعطيني الفكره الأساسية او الشىء الي اقدر استخدمه واحله منها
السؤال الأول :
A boat travels a distance of 34.0 km 20.0o North of East. It then travels 74.6 km in a direction 30.0o West of North. How far to the West is the boat from where it started? Give the answer in km and give three significant figures.
السؤال الثاني :
Vectors A, B and C are related by the equation: C = A + B. If vector A has a magnitude of 11.8 and makes an angle of 110° with respect to the x-axis and vector C has a magnitude of 7.7 and makes an angle of 170° with respect to the x-axis, what is the angle vector B makes with the x-axis? Note angle measured in counterclockwise direction is +ve, and give your answer as +ve quantity - i.e. measured counterclockwise.
في إنتظار ردودكم
تحياتي لكم
